1 to 4 player co-op survival horror

You wake up
owing a debt
to a fire.

A frozen valley. No memory of how you got here. A camp that is not yours, a radio playing music from a hundred years ago, and a fire that eats more every night. Feed it, or don't wake up.

Pitch & Pillars

Lethal Company has the deadline. Content Warning has oxygen. R.E.P.O. has fragile cargo. We have the cold, and the fire as the one thing holding it back.

The fire is the chain. It feeds you warmth, light, food, and progression, and in exchange it owns your schedule and your economy. Every day you range out for fuel and materials. Every dusk you scramble home. Every night you sleep, and the fire spends what you stocked.

The five pillars

  • The fire is the chain. Every system routes through the fire, the cold, or the distance from camp. If a feature touches none of those, it probably doesn't belong.
  • No walls, no timers on screen. Pressure comes from things you can see and feel: falling light, rising wind, the storm wall, the warmth bar. You CAN walk into the dark. It will kill you, and that was your call.
  • The story stays in the background. A player who skips every note and never touches the radio still gets a complete game. The lore is there for the ones who go looking.
  • Danger is distance. The farther from the fire, the better the loot and the worse the odds. The map is the difficulty curve.
  • Friendslop first. Two-man carries, arguments over what to burn, someone sprinting home at 2 percent warmth screaming on voice. Systems should generate stories, not tutorials.
The formula check Do the thing (day expedition) · come back to base (dusk scramble) · base phase (cabin evening, stock the fire, sleep) · repeat with higher stakes. That is the friendslop skeleton, intact. Our twist: the base phase ends in a bet. You sleep, and the fire either holds or it doesn't.
02 / Game

Setting & Lore

Each player just woke up here. No memory of arriving, no idea where "here" is.

In co-op, everyone wakes in a different spot around the camp and converges on the fire because it is the only warm thing in sight. The camp is clearly lived-in and clearly not yours: the tent, the drying rack, a half burned journal, a radio playing a 1925 record to nobody. Up the hill there are seven graves. Nobody explains them.

The first legible line of the journal is the only tutorial the story gives: "feed the fire."

Rules for the writing

  • The story never interrupts the game. No cutscenes, no forced reads, no lore gates.
  • Drip feed, never dump. Every note answers one question and raises two.
  • The entity, if there is one, is never named and never shown. What the player gets is wrongness that accumulates.

The wrongness

  • New resources appear in the valley overnight, but never near the fire. The valley provides, but never where you are.
  • Every clock in every ruin is stopped at the same time.
  • The moon does not move.
  • The radio only picks up music from about a hundred years ago. Sometimes it slips, like the band drops somewhere darker for a second.
  • Things left outside the cabin overnight are gone by morning. Something takes them.
  • The graves. Count them at the start of a run. Maybe count them again later.

Identity fragments

Rare finds that seem to belong to the players themselves: a photo, a watch with initials, a train ticket. Were you here before? Are you one of the graves? Never answered.

How much gets answered One real revelation, deep in the valley, for groups that push all the way out. Everything else stays ambiguous. Friendslop groups don't want a codex, they want one "wait, WHAT" moment per ten hours.
03 / The Loop

The Day Loop

One day is 10 to 15 real minutes. Four beats. This replaces the old night-gathering loop entirely.

DAWN
DAY · the venture
DUSK
SLEEP
wake · read the night's evidenceeverything competes for daylightscramblethe bet
Dawn
Wake in the cabin. Read what the night did: tracks, marks, what's missing.
Day
Venture out. Gather, haul, explore, craft, fish. Daylight is the only currency.
Dusk
Sprint home. Haul everything inside. Stock the fire rack.
Night
Sleep vote. The fire spends the rack. Overnight resolution.
↺  next dawn: quota is higher, near resources are thinner, the frontier moves outward

Dawn is the reveal. Overnight resolution already happened while you slept: the fire ate its quota, the Offering Stone resolved, new resources appeared somewhere far out, and the night left evidence. Fresh tracks circling the cabin. Claw marks on the door. The sled someone forgot outside is gone.

Day is everything. Gathering, hauling, feeding the fire, crafting, the Offering Stone trek, cabin building, fishing. All of it competes for the same daylight. The core question of the whole game: is this worth the daylight it costs?

Escalation is spatial. The quota grows nightly. Nothing respawns near camp; new spawns land farther out. The harvest frontier expands outward at roughly the speed your gear improves. Nobody ever tells the player to explore. The fire's hunger does.

04 / The Loop

Dusk

The signature beat. It has to feel like an extraction, not a curfew.

The world is the clock

No countdown UI, ever. The player reads dusk from stacked natural signals:

  • Light shifts amber, then blue. Shadows stretch.
  • Wind picks up. The blizzard audio changes register.
  • The storm wall on the horizon starts moving in, visible from almost anywhere.
  • Wildlife audio drops out. Then the first calls start, far off.
  • Warmth drain begins creeping up even in daylight gear.

Veterans read the wind and call the turn. New players learn by nearly dying once. Both of those are the game working.

The ramp, not the cliff

The clip test The clip we want: a player limping in at 2 percent warmth while the squad screams on voice. The clip we don't want: a player dying to a clock they could not see.

The scramble checklist

  • Everyone back inside the light, then inside the cabin.
  • Haul every loose resource indoors. Anything left outside is gone by morning.
  • Stock the fire rack to quota. Then argue about overfeeding.
  • Optional: leave an offering on the stone, if someone made the trek.
05 / The Loop

Night & Sleep

Night is a sleep phase, not a play phase. Going outside at night deals heavy cold damage even next to the fire. The night belongs to the valley.

  • Sleep vote. All players in a bed starts the night.
  • Staying up is not free. The fire keeps burning your night stock in real time while you dawdle. "One more craft" has a price. (Experiment flag: try a paused variant later, compare the feel.)
  • The transition is an audio scene. Wind. The fire settling. Footsteps in the snow outside. Something brushing the cabin wall. The radio clicking on by itself for three seconds. You skip the night, but you hear enough of it to dread it.

Overnight resolution

1 · The rack burns
The fire pays its nightly quota from whatever was stocked at nightfall.
↓ how much was in the rack?
SurplusThe extra accumulates toward the fire's next growth stage.
Barely enoughDawn: fire is low. You wake fine, but the evening light will be thin.
ShortDawn: frostbitten. Warmth debuff day for everyone.
StarvedThe fire dies. Nobody wakes up. Run over.
2 · The stone resolves
Anything left on the Offering Stone is exchanged. Nobody sees it happen.
3 · The valley moves
New resources spawn in the outer bands. Night evidence is placed. Anything left outside is taken.
↓ DAWN
Hard rule · left outside is lost Resources, tools, the sled: anything not brought indoors is gone by morning. Something takes it. This turns the dusk cleanup into gameplay and doubles as lore. Drag marks leading into the treeline sell it as fiction instead of a bug.

The 3 AM emergency

The one sliver of night gameplay, kept rare so it stays terrifying. If the fire is starving mid-night, one player gets shaken awake: the fire is dying. Dash out in lethal cold, maybe 30 seconds of survivability, throw fuel on, get back inside. Everything outside is active. A punishment and a story generator, not a routine.

Morning evidence

The night always leaves a note. Tracks circling the cabin. Claw marks. A shutter open that was closed. Evidence scales with how deep into the run you are and how close the fire came to dying. It is the horror payoff for a night you never see.

06 / Systems

The Fire

The outdoor bonfire at the center of camp. It is supernatural and we never explain it. It was burning before you woke up.

It stays outdoors forever, no indoor hearth: the fire is the landmark, the town square, and the god you pay rent to. The fire is why you wake up tomorrow. That is its whole design.

The rack, the quota

Next to the fire stands the log rack. What is in the rack at nightfall is what the fire has to survive on. The rack IS the quota interface: one glance says "we are 20 burn short tonight."

The quota is the fire's nightly appetite in burn value, and it rises every night. Starting point for tuning: night one around 20 burn, roughly +30 percent per night. The first night is easy on purpose. The curve gets mean.

Overfeeding: growth stages

Surplus beyond quota is never wasted. It accumulates toward the fire's next growth stage, and at each stage the team chooses what the fire becomes. No menu. The choice happens at the fire, and the fire physically changes: bigger pit, taller flame, new stone ring. The fire's size is the team's progress bar, visible from across the valley.

WIDE

Bigger light radius. A bigger safe zone at camp in the evening hours.

HOT

Faster warm-up when you return. Unlocks the cooking tier.

SLOW

Burns less per night. Directly eases every future quota.

Failure, graduated

Rack at nightfallDawn result
Short by a littleEveryone wakes frostbitten. Warmth debuff for the day.
Short by a lotThe fire dies overnight. The cold takes you in your beds. Run over, score is days survived. Quiet, brutal, fits the tone.
Starving mid-nightTriggers the 3 AM emergency instead of instant loss.
Design decision The fire dying is a dawn event, never a mid-day one. During the day the fire can burn LOW (thin evening light, rising tension), but the kill condition only resolves overnight. Keeps the day free for play, keeps the bet framing clean.
07 / Systems

Burn Economy

Everything you can pick up has a burn value, the way Lethal Company scrap has a sell value. The fire is the counter you sell it to.

One number, one verb (throw it in), two outcomes (survive tonight, grow the fire).

ItemBurnNotes
Branch / twig bundle2ground pickup, everywhere
Log5from chopping trees
Plank4ruins, crates
Coal lump12ore outcrops, mid valley
Kerosene can25ruins, far valley, rare
Book3ruins, light and stackable
Chair12one-hand carry
Bookshelf25two-man carry
Grandfather clock45two-man carry, slow, comedy gold
Pelt6better used at the workbench
Rope coil10better used as a tool

Numbers are placeholders. The shape matters: junk hauling should out-earn stick gathering per trip, and premium fuel from deep zones should out-earn junk. Distance pays.

The beehive tension Some items are worth more unburned. A rope coil, a medkit, a lantern: decent burn value AND a better use. Short night, low rack: does the rope go in the fire? Never resolve this with a warning dialog. Let people burn the medkit.

Two-man carries. Big furniture needs two players, moves slow, blocks sprinting. Deliberate friendslop: the armoire hauled through a blizzard at dusk is the story the group tells afterward.

No gold, no shop. The old currency loop is dead. Materials go to the workbench, burnables go to the fire, weird things go to the stone. Three sinks, no currency.

08 / Systems

The Cabin

You start with the tent that was already in the camp. Building the cabin is the first team project.

Tent
Days 1 to 3ish. Weak shelter: the fire must burn hotter overnight, and you hear EVERYTHING through the canvas.
Frame
Planks, nails, hinges, a saw. Materials only exist out in the ruins.
Cabin
Solid shelter. Built in visible stages, progress every day.
Upgrades
Insulation, storage, beds, the window.
UpgradeEffect
InsulationThe fire burns less overnight. Directly eases the quota curve. Probably the highest-value upgrade in the game.
StorageRacks and shelves inside. More "indoors" capacity for the left-outside-is-lost rule.
BedsBetter sleep. Maybe removes the frostbite floor on a short night.
The windowShutters you can open to peek out at night. Pure horror flavor, zero mechanical value. You will look exactly once.

Indoors is a real state. It is where resources are safe overnight, where you sleep, where the night cannot reach. No door-holding minigame: the cabin holds as long as the fire does. The threat at the walls is audio and evidence, not a breach mechanic. Keep it that way until playtests demand otherwise.

The radio moves in with you. It survives the upgrade.

09 / Systems

Warmth & Cold

The cold is the antagonist. Warmth drains with distance, weather, wetness, and hour. It refills near heat.

Warmth as the leash

There is no wall around the camp and no rule that says stay close. Early gear gives you maybe 90 seconds of comfortable range. That is the leash. Every gear upgrade visibly extends the radius you can work in, so progression is exploration range. Range is earned, not unlocked by a timer.

Fire
Warm. Safe. Home.
Near
Slow drain. Early gear works.
Mid
Fast drain. Needs a coat.
Far
Severe. Full kit plus planning.
  • Weather: blizzard gusts spike the drain. The always-storming baseline stays, it is the identity of the place.
  • Wet: falling into the pond or lake doubles the drain until you dry by a fire.
  • Hour: late dusk multiplies the drain. Night is lethal in under a minute, even beside the fire.
  • Health: one bar (hunger folded in). Warmth at zero drains health fast. Shivering and screen frost telegraph the stages.

Secondary hearths. Some ruins have fireplaces you can light and feed. A forward base extends your working range but splits the fuel economy. "We cannot afford two fires" is a great argument for a group to have.

10 / Systems

The Workbench

The mundane half of progression. A bench in camp where scavenged materials become personal gear.

The split that matters: the fire is team progression, the workbench is your loadout. No shop, no gold, no magic. That all lives elsewhere.

GearMaterialsWhat it does
Coatcloth ×3, pelt ×2slower warmth drain, the range extender
Glovespelt ×1, cloth ×1faster chopping and hauling in cold
Snowshoesplanks ×2, rope ×1normal speed in deep snow zones
Lanternscrap ×2, kerosenecarried light, better than the flashlight, uses fuel
Better axescrap ×2, planks ×1fewer swings per tree
Ice pickscrap ×3opens frozen lake holes faster
Sled repairplanks ×2, rope ×1the haul multiplier
Bandagescloth ×2, herbs ×1heal kit
Flarescrap ×1, coal ×1scares monsters, marks a path home

Placeholders. Recipes should read at a glance and use at most three material types.

The sled The haul multiplier and probably the most contested tool in the game. One player drags it (slow), it carries what four hands cannot, and if it is left outside at dusk it is GONE by morning. Sled discipline is team discipline.

Crafting happens AT the bench, physically. UI shows recipes only when you are standing there. The cabin build and its upgrades run through the same materials pool: coat now or insulation now is a real argument.

11 / Systems

The Offering Stone

A flat stone slab out at the old chapel. The one system that touches the supernatural directly, and it never says a word about itself.

Day
Place an item on the stone.
Sleep
The exchange happens. Nobody sees it.
Dawn
The item is gone. Something else waits in its place.

The rates are the content

Nothing is documented in game. The exchange table is discovered by experimenting, and that knowledge is the reward: it becomes group lore ("pelts get you nothing, leave TEETH") and spreads between friend groups outside the game.

OfferedReturned
Monster drops (teeth, antler, core)The good stuff: charms and impossible gear
A personal identity fragmentSomething painful and strong. You gave up a piece of who you were.
Mundane junkNothing. Or an insult: a single twig.
FoodA dead bird? The stone has opinions.

Impossible gear

Small passives and weird actives that mundane crafting can never make. A lantern that burns nothing. Boots that leave no footprints. A charm that makes the wolves hesitate one beat longer. One slot per player at first. Keep the power ceiling low: these are spice, not builds.

Deals with a price

Some returns cost more than the offered item: a max warmth chip, a voice that sounds wrong on proximity chat for a day, the radio refusing to play your song. Rare, always survivable, always story-worthy. The target sentence: "who let Dave take that deal?"

Rules Never explain. No lore note documents the stone. It never advances the quota (a side bet, skippable entirely). One offering per night to start.
12 / Systems

Fishing

Built and playtested already. Mechanics modeled closely on Gone Fishing, with a Dead by Daylight style skill check. Survives the redesign nearly unchanged.

A daytime activity that feeds people, fished from the pond near camp (shallow, safe, in view of the fire) or the frozen lake holes (better fish, farther, colder).

Cast
Hold LMB to wind up. Power sets distance (3.5 to 17m). Release, and the bobber flies a real arc. Land on dry ground: it plops, auto-reels, "that's not water."
↓ wait for the dip
Hook · skill check
A circular check: needle sweeps, hit the green zone to set the hook. The bright center is a GREAT hook (wider green zone, faster reel). Miss, and it got away.
↓ hooked
Reel · tension
Hold LMB to reel, release to give line. Keep tension in the green. Pegged tension SNAPS the line. Slack line and the fish shakes loose. Mid-reel THRASH: surprise SPACE checks.
↓ progress bar full
Caught
Splash, +1 fish. Cook it tonight.
Economy guard Fish are food, and lousy fuel on purpose. Never let fishing feed the quota or it becomes the boring optimum. Possible spice: some fish are worth OFFERING rather than eating.
13 / Systems

Food & Cooking

Light system, deliberately. No hunger bar. Food restores health and grants short warmth buffs, so eating well extends how hard you can push out.

  • Berries: bushes in the near and mid valley. Eat raw, small heal.
  • Fish: the main renewable. Raw is a poor meal, cooked is a good one.
  • Soup: pot over the fire, needs the HOT stage. Fish or berries plus herbs, best meal, feeds the team.
  • Rations: rare ruin finds. Good, instant, nonrenewable, and they carry lore weight. Whose rations were these?

Cooking requires the fire's HOT growth stage, which makes HOT a real competitor to WIDE and SLOW, and makes the cooking unlock feel like the camp maturing. Cooking is diegetic: pot on the tripod, put things in, wait, ladle out.

Not doing: spoilage, cooking minigames, recipe discovery trees. Food is fuel for people. The interesting decisions live elsewhere.

14 / The World

The Valley

A snowed-in valley ringed by impassable mountains. Procedurally generated per run from a seed, with authored structures dropped in by rules. Always storming. The world reveals itself in layers.

Danger is distance

  • Campfire, cabin, pond. Safe.
  • Near valley · 0-150mwood, berries, small ruins. Wolves passing through.
  • Mid valley · 150-350mcoal, the lake, ranger station, chapel. Wolf packs, the Frozen.
  • Far valley · 350m+kerosene, rich ruins, the lodge, the mine head. The Wendigo.
  • The deepthe wastes, the dark treeline. The Ice Worm. And the one real answer.

Zones keep their names: Frostpine Forest, the Frozen Lake, the Frozen Wastes, the Deep Dark. Fixed compass bearings with seeded jitter, so maps are learnable across runs but never identical.

The storm wall

The whiteout is a visible storm front at the valley edges, and it closes in at dusk. It reads as weather, never as a wall, but it does the wall's job: it defines the playable space and the day's end. Walking into it is allowed. Visibility drops to arm's length, warmth drains several times faster, and the audio goes wrong. People will test it once.

No reset The valley does not reset. Trees you chop stay chopped. Ruins you strip stay stripped. New resources spawn overnight in the outer bands only, never near the fire. The world is consumed outward, like a fire eats a log. That is on purpose, and it is also the lore.
15 / The World

Structures

Authored places dropped into the procedural valley by rules. Each one answers a piece of "where am I" and carries loot for its band. The ruins are the junk economy AND the storytelling.

The watchtower moment Lighting a watchtower is the best team moment we can build cheaply: costs fuel, takes a climb, and from then on there is a light on the horizon that says home is THAT way. Navigation, progression, and a shared "we did that" in one object. Build this one early.

Design rules

  • Every structure readable as a silhouette in bad visibility from 40 meters.
  • Every structure has at least one thing to burn, one thing to use, one thing to read.
  • Never lock progress behind a structure. They are optional gravity, not gates.

Scarcity model

  • Nothing respawns near camp. The near valley is a starter package, not an income.
  • New spawns appear overnight in the mid and far bands only. The valley provides, never where you are.
  • The practical effect: the harvest frontier expands outward at roughly the speed the quota grows. If tuning is right, teams always feel slightly behind.

Strip the near valley.
Day 3-5
Coal runs, first ruins, cabin build.
Day 6-9
Far ruins, kerosene, forward hearth.
Day 10+
The deep. The answer. Or the fire wins.

Anti-hoarding: the left-outside-is-lost rule plus finite indoor storage keeps stockpiles honest. You cannot bank ten nights of fuel in a pile behind the cabin. The game stays about tomorrow.

17 / Monsters

The Roster

Every monster is a rule you can learn, and every rule has a counter you can execute under pressure. Deaths should feel like broken rules, not bad luck.

With night gathering dead, monsters are no longer the night threat. They are distance threats (each species owns a band), dusk threats (a couple get bold as light fails), and the night itself, which is never seen and never fought.

Frost Wolves

near/mid · day, bold at dusk · the comedy engine

Packs of 2 to 4. They shadow you, probe whoever is isolated, and commit at dusk. They target the carried, the slow, and the separated. Dropping your haul makes you faster, and that decision is the design. Drops: pelts and teeth.

The rulePacks probe before they commit. Fire, flares, and sticking together hold them.

The Frozen

ruins · always · the dread

People who did not make it, still standing where the cold took them. Dormant until proximity or noise, and a dormant Frozen looks a lot like a snow mound. Slow, short leash, hits like a truck. Sometimes one wears something you recognize.

The ruleYou do not fight the Frozen, you manage them: bait, distract, grab, leave.

The Wendigo

far valley · dusk · the terror

One per run. Maybe zero, and the maybe is important. It stalks, it freezes when watched, and the blizzard spends your sightlines for you. When it commits it takes ONE player, drag-style, and retreats. Sometimes the right call on a rescue is no.

The ruleEye contact holds it. The kill condition is the second time you lose track of it.

The Ice Worm

the wastes · day · the spectacle

Lives under the flat snow of the wastes. Hunts vibration. Telegraphs: a rumble in the audio floor, snow shivering in a line. The burst commits to a line and is dodgeable. The sled cannot dodge. Not killable, always avoidable: terrain that hates you.

The ruleSnow that looks TOO smooth is its ground. Stay on rock.

The Night

the cabin walls · night · never seen

Audio while you sleep. Evidence at dawn. The thing that takes what you leave outside. No model, no health bar, no name, ever: the moment the night is a creature you can point a flashlight at, the game gets smaller. Morning evidence scales with how close the fire came to dying. Players will infer that a well-fed fire keeps it farther out, and they will be right, and we never confirm it.

The ruleStay inside. That is the rule.

Tone budget: wolves are comedy, the Frozen are dread, the Wendigo is terror, the Worm is spectacle, the Night never shows itself. A session should hit at least two registers.

Combat stays light: melee, flares, firebombs. You can drive things off, but combat is a tax, not an income. Drops feed the Offering Stone, which is the only reason to pick a fight on purpose.

18 / Co-op

Co-op & Roles

1 to 4 players, proximity voice, roles emerge and are never assigned.

The hauler

Drags the sled, does the two-man carries, hates the wolves.

The forager

Chops, picks, fishes, keeps the rack fed.

The scout

Pushes the frontier, finds ruins, carries flares and map fragments.

The keeper

Tends the fire, cooks, crafts, does the dusk cleanup, yells at everyone.

A duo doubles up. Solo does everything, and the tuning must respect that: quota scales with lobby size.

Proximity voice from day one of netcode. Distance and the blizzard muffle voices. Shouting has a cost in wolf country. This one feature carries half the genre.

The daily arguments (the actual content)

  • Overfeed the fire, or bank materials for the cabin?
  • Burn the rope, or keep the rope?
  • Push one more ruin, or turn back now?
  • Whose fault was the sled?
  • Take the Offering Stone deal, or not?

Design systems that put two good answers in the room. The argument is the game.

19 / Co-op

Death & Failure

Individual death stays cheap and funny. Team failure stays existential and shared.

You die out there
Body stays where it fell, full pack on it.
Spectate
Watch your friends until dawn. LC rule, do not innovate here.
Dawn
You wake in your bed. No explanation given, none needed.
The body run
Your gear is still on your corpse. Built-in quest with a route decision.

Death costs a day of gear and a body run, not the run itself. The valley does not let you leave that easily, which is lore if you squint. Solo death skips to dawn the same way.

The run ends one way The fire dies overnight. Understocked rack, or a failed 3 AM emergency. Dawn light on a cold fire pit, then the score: days survived, fires grown, ruins found, deepest point reached. Nobody gets voted out of a run by one bad wolf. The only way to really lose is together, at the fire.

Meta progression: none for v1 beyond stats and scoreboards. Runs are self-contained.

20 / Tech

Current Build vs Redesign

The Unity prototype is deep into the old design. Here is what carries, what changes, and what dies.

Carries over as-is

  • The valley generator: seeded terrain, zones, mountain ring, forest, structure placement.
  • Warmth, health, wet, movement feel, footprints, blizzard, the lighting.
  • The full fishing system. The pond with real water and diving, the frozen lake.
  • Monsters as creatures (bodies, animation, voices, hit feedback). Their placement logic changes.
  • The tent radio: public domain 1920s records through the haunted AM filter, opens on The Prisoner's Song.
  • Camp art, asset pipeline (Kenney, Quaternius, CC0 audio), the Lethal Company filter, HUD framework, debug tools.

Changes meaning

  • Day and night INVERT. Day is the play phase, night is the sleep phase. Night-only gathering dies.
  • The fire: from quota-meter-with-upgrade-menu to rack, burn values, growth stages.
  • The tent: from set dressing to the starting shelter of the cabin arc.
  • Resource regrowth: from reset-at-dawn to no-reset with outer-band overnight spawns.
  • Camp confinement DIES. Replaced by the warmth leash, the dusk ramp, the storm wall.
  • The enchanting table splits into the Offering Stone (at the chapel) and the Workbench (in camp). Shop and gold die.
  • Monsters redistribute from night waves to distance bands plus dusk boldness.

Dies entirely

Night gathering · the intermission · the whiteout hard wall · fire upgrade menus · the shop · gold · the spell system (anything worth keeping folds into Offering Stone charms) · night spawn waves.

Netcode (unchanged, deferred)

NGO host-authoritative, Steam lobbies and relay, Dissonance proximity voice. The redesign makes the hardest sync window disappear: night is a sleep cut, so overnight resolution happens on the host while everyone stares at a black screen. Free lunch. Two-man carries and the sled stay hard. Do not start netcode until the solo game survives ten playtest days without design churn.

21 / Tech

Pivot Roadmap

Ordered so the game is playable after every step. Single player first, netcode after the loop proves out.

1

Invert the loop

Day timer with a sun arc, dusk ramp, lethal night. Remove CampConfine and night-only gathering. Beds, sleep vote, cut-to-black audio scene, overnight resolution stub, dawn wake. Repurpose the nightfall FX into the dusk warning sequence.

✓ playable: a full day-sleep-day cycle with the fire consuming overnight

2

The burn economy

Burn values on everything, the log rack (deposit interaction, fill readout), quota as overnight rack consumption with graduated failure. Junk items in ruins including two-man carries. Fire growth stages with the WIDE/HOT/SLOW choice. Remove the fire upgrade menu.

✓ playable: the LC feeling. Haul junk home, argue, stock the rack, sleep on a bet

3

Exploration pays

No-reset resources with outer-band overnight spawns. Materials in ruins and from wildlife. The workbench with the first recipe set. The left-outside-is-lost rule and morning evidence.

4

The weird

The Offering Stone at the chapel (overnight exchange, first rate table, one charm slot). Night audio scenes, the 3 AM emergency. Identity fragments, journal pages, map fragments, radio frequencies.

5

The cabin

The build arc in stages, insulation, storage, beds, the window. The tent retires.

6

Monsters rehomed

Distance-band spawns, dusk boldness curves, the Frozen guarding ruins, the Worm with telegraphs, the Wendigo far-band stalker. Watchtower lighting, secondary hearths.

7

Netcode

NGO, Steam lobby, proximity voice. Only after the solo loop is fun.

Estimate honesty: phases 1 and 2 change the game's spine and should come as one continuous push. Everything after is separable.

22 / Parking Lot

Open Questions

Staying up past dusk
Current call: the fire burns real night stock while you dawdle. Experiment flag: try a paused variant later, A/B the feel.
Quota curve numbers
Start 20, +30 percent per night is a guess. Tune against real hauls.
Growth stage choices permanent?
Lean permanent. Choices should scar.
Frostbitten dawn: recoverable or death spiral?
Needs testing. Add pity valves if spiral.
The ember lantern
A carryable piece of the fire that burns down and forces a return trip. Still attractive, unclear if the new loop needs it. Park until Phase 3 plays.

Lean improve only. Scope control.
The tent afterlife
Keep, store, or burn it for 30.

Park until the first one proves out.

Needs a downed-state design first, or drag replaces down.
Meta progression for v1
Current call: none. Score only. Shareable run seeds are a free feature if determinism holds.
