Systems

What you'll feel.

Eight interlocking systems do most of the work, plus the Wrought — one optional path that costs more than it gives. None of them are survival-lite. None of them have a clean answer. Tradeoffs generate the game's best stories — not scripted events.

Pillar 01 — The Mech Is Who You Are
SYS / 01 / MECH

Your mech is your lifeline.

A hulking, cobbled-together machine that serves as your transport, your combat platform, and your mobile base. It starts broken. You earn every upgrade by scavenging the most dangerous corners of the map.

The mech is fully modular — every component is a discrete entity with stats, visual representation, and wear state. Swap legs for treads. Bolt on new weapons. Mount defensive plating scavenged from a ruined factory. Every mech becomes a reflection of where you've been and what you've survived.

And because mech parts degrade and break in combat, you're always one bad fight away from being stranded on foot in a blizzard. Being without the mech is a meaningful degraded gameplay state, not a brief inconvenience.

Modular parts Wear & durability Mount or dismount
Pillar 02 — Every Decision Has Weight
SYS / 02 / SURVIVAL

Survival that means something.

This isn't survival-lite with a hunger bar you occasionally top off. Desolation Engine models nutrition, body temperature, pain, illness, and addiction — all interlocking, all compounding.

Solving one problem can worsen another. Your gear has real weight, and that weight affects stamina, speed, and how many swings of a hammer you can take before you're gasping. Backpacks can be dropped mid-combat to move faster — a mechanic that creates genuine tactical moments.

The environment itself is hostile. Blizzards reduce visibility to nothing. Crevasses swallow the careless. Nights are long and cold. The weather isn't atmosphere — it's a gameplay system that changes how you approach every expedition.

Nutrition Temperature Pain Illness Encumbrance
Pillar 03 — Deliberate, Strategic, Punishing
SYS / 03 / COMBAT

Deliberate. Strategic. Punishing.

There's no auto-aim, no hitscan — projectiles have travel time influenced by weapon accuracy and your character's skill. Every fight risks damage to your gear and your mech, and repairs cost resources you might need to survive the journey home.

Enemies are smart. AI opponents prioritize cover, seek high ground, and retreat when wounded. You'll face hostile scavengers, mutated wildlife, and massive artillery mechs flanked by drone scouts. Take out a mech's sensor drones and it fires blind — that kind of emergent tactical play is baked into the design.

There are no classes. Your build comes from the traits you choose at creation, the skills you learn from trainers and books scattered across the wasteland, and the gear you carry. A gunslinger who eats less and moves light plays completely differently from a heavy melee brawler in power armor.

Pillar 04 — Scarcity Has a Memory
SYS / 04 / ECONOMY

The merchant remembers.

Every settlement runs its own economy. Scrip is the post-collapse currency — genuinely scarce, locally trusted. There's no global market, no fixed prices, and no merchant who hasn't heard of you.

Trade is a relationship system. Inventories reflect what each merchant has actually scavenged. Prices reflect what they think you can afford and what they think of you. A trader who's been told you cheated someone in a neighbouring camp prices you accordingly. A trader you've defended from a raid carries items they wouldn't sell to anyone else.

Buying becomes a form of social positioning. Who you trade with says where you stand.

Scrip currency Local inventories Reputation memory
Pillar 05 — Knowledge Has a Body
SYS / 05 / CRAFTING

What you make is what you survive.

Crafting and cooking aren't menus. Both are physical activities at specific stations: a campfire, a forge, a workbench. Each station is a real-world object you build or find, requiring fuel, time, and the right tools.

Recipes are knowledge, not inventory. Your pawn learns recipes from books, mentors, and trial-and-error in the wilderness. When that pawn dies, recipes drop as a tangible data shard alongside the body — recoverable, losable, tradeable. The next pawn doesn't auto-inherit what the last one knew.

Cooking specifically matters: hot meals warm the body and lift the mood. Eating cold rations keeps you alive but doesn't keep you sane.

Stations Recipes as knowledge Cooking + mood Recoverable shards
Pillar 06 — The Map's Politics Aren't Decorative
SYS / 06 / FACTIONS

Settlements move. Factions remember.

Factions are not static map-fillers. Each has goals it pursues across the calendar — territorial ambitions, resource demands, internal politics — and acts on them whether the player is involved or not.

Settlements have viability scores that tick against weather, faction relations, and resource depletion. When viability falls, populations migrate — pack up, walk across the map, and reseed somewhere new. Possibly closer to you. Possibly into the territory of someone they used to be at war with.

The sabotage system gives you tools to intervene without combat. Cripple a generator, block a fuel line, blow the seal on a heat exchanger. A noise profile determines whether you're caught. A technician AI determines whether the damage gets repaired before it cascades. Patient violence — the cold takes care of the rest.

Negotiation matters too. Faction dialogue is gated behind reputation and tradeoffs. Broker peace. Play sides. Betray both, walk into the smoking ruins, and pick clean.

A Specialty Build — Optional, Trait-Gated
SYS / OPT / WROUGHT

You were not chosen. You were changed.

A grounded, horror-inflected take on psychic ability. Dune Navigators, not Warhammer battle-mages: small powers, permanent costs, slow deterioration, and a world that reacts with fear or reverence when it sees the signs.

∎ The Wrought Suppress · walk through the world unseen
∎ Sense

Extended perception. Feel life signs through walls, read emotional residue from objects, perceive nearby threats through fog and darkness. Cost: gradual vision degradation.

∎ Push / Pull

Crude telekinetic force. Throw someone off their feet, jam a heavy door, retrieve a dropped item. Cost: muscle and tendon damage in arms and back.

∎ Burn

Generating heat from within. The most obvious survival utility in an eternal winter — but using Burn to stay warm is a trap. Cost: skin, internal organs, massive nutrition drain.

∎ Read

Psychic imprinting from objects or locations. Touch a corpse and get fragments of their final moments. The primary lore-delivery mechanism for the Wrought. Cost: chronic migraines.

∎ Suppress

Dampening other Wrought — or, more interestingly, suppressing yourself. A character who refuses to use their gift walks at half the risk. Cost: passive nutrition drain.

∎ The Ledger

Rustblight is the degenerative condition that begins the first time you use a power. Incurable. Manageable. Late-game Wrought are living on borrowed time, and the player feels every power they spend.

If a player finishes a Wrought run and says "I wouldn't do that again," the system is working.

Pillar 07 — The World Doesn't Wait
SYS / 07 / SUCCESSION

Death is not the end. But it hurts.

When you die, the world keeps going. Your old character's body stays where it fell, along with all their gear and their mech.

You create a new survivor who picks up a distress beacon pointing to the remains of whoever came before. Time passes between deaths — and how much time has passed changes what you find when you get there. The mech may have been scavenged. A faction may have moved through. A creature may have made a den of the cockpit.

This creates a roguelike tension layered over a persistent world. Every life matters, but death isn't a hard reset — it's a new chapter.

If the player chooses not to recover the body — or cannot reach it — the new pawn starts that chapter blind. The calendar has moved on. The knowledge is lost unless it can be reacquired from surviving sources in the world.

Pillar 08 — How It Ends Depends on How You Lived

Five end states. None of them are written toward.

The endings are read out of the simulation at the moment of resolution. What determines the ending is a set of world-state variables: which factions are alive, what their relationship to the player is, whether the player has accumulated the necessary knowledge, and how much time has passed.

#End StateWhat it requires
01 Escape Mech fully repaired; player finds an exit route. The truth behind The Dimming undiscovered. Always available as a baseline.
02 Witness The player uncovers what is really behind The Dimming. They cannot stop it. They document and transmit what they learned. Requires deep faction/NPC access.
03 Intervention The player acts on the discovery — sabotage, alteration, or interface. Requires the simulation to be healthy enough that the necessary factions still exist and trust the player.
04 Acceleration The player's actions hasten the very thing they were surviving. The simulation has collapsed below the threshold where constructive action is possible. Tragic, not punishing.
05 The World Moves On The player dies too many times; time passes beyond a terminal threshold. The game ends not with a climax but with a final journal entry, found by no one.

No ending is locked behind a single choice. They emerge from the accumulated state of the run.
