Red-lit combat: a survivor firing on a cluster of zombies as one bursts apart, rifle in frame

contact — sector 7, wave 14

File 01 — field systems

Everything you carry can be upgraded. Everything hunting you adapts.

Old-school round-based survival welded to a modern gear economy. Every run is a race to out-build the horde before it out-numbers you.

01 · ARSENAL

Pack-a-Punch

Feed the machine your points; walk out with a re-tiered weapon — more damage, bigger mags, new firing behavior. Every gun has a ladder.

20+ weapons · 4 upgrade tiers

02 · PERKS

30 Perks on Tap

Speed-reload, revive-fast, double-tap, electric reload nova, spare ammo — wall machines all over the map, each with a trick.

30 perks · stackable

03 · DEFENSE

Nail It Down

Press Q, grab a crate, hammer it into the doorway. Barricades have real HP and armor — and the horde tears through if you stop repairing.

Physical cades · repairable

04 · LOADOUT

Grid Inventory

A real bag with weight, gear slots and item stats. Rotate items into the grid, equip a helmet and chest rig, right-click to use meds on a specific limb. Seven body zones — every one can bleed, fracture, or fail. (This whole page is styled after that in-game paper HUD.)

Grid bag · 7 gear slots · limb health

05 · HARDWARE

Buy, Place, Reclaim Turrets

Turrets are deployables from the arsenal crate. A green ghost shows where they stick, red where they won't — place it and it mows the horde. Hold shift to pick it back up when the wave shifts.

Auto · Flame · Tesla · Cryo · Rocket

06 · MOBILITY

Teleporters & Traps

Link pads to build a base and train the horde into a kill-box. Wire electric traps and let the map do the work.

Base-building · zombie trains

File 02 — requisition

Pack-a-Punch it.

Every weapon has an upgrade path. Bank the points, feed the machine, watch the numbers climb. Flip the stamp to see what a re-tier does — then pick a different gun.

AK-47+++ TIER II

File 03 — specimen dossier

Know what comes through the door

The horde isn't just numbers. Specials break your formation, drag you off the line, and force the fight to move. Every wave mixes the roster — and it only gets meaner.

SPEC-01 · COMMON

Walker

Slow, relentless, never alone. The mass that eats your cades and your ammo.

ThreatLow

SPEC-04 · SPRINTER

Runner

Closes the gap before you can reload. Punishes anyone reloading in the open.

ThreatMed

SPEC-07 · SCREAMER

Howler

Summons a fresh pack and scrambles your HUD. Kill it first or drown in adds.

ThreatHigh

SPEC-09 · GAS

Bloated

Bursts into a toxic cloud on death. Great at close range — for the wrong team.

ThreatHigh

SPEC-00 · BOSS

Demon

The thing containment failed on. A round-ending boss that soaks a whole team's firepower.

ThreatCritical

File 04 — personnel

Pick your survivor

Every operator drags a different edge into the breach — speed, muscle, or field medicine. More get cleared for duty the deeper your squad pushes.

OP-00 · Vanguard

Vera

The reference survivor. Balanced across the board, no weak spot — learn the lab on her.

Balanced loadout

OP-04 · Flux

Quantum

Moves fast, reloads faster. Built for kiting the horde and running trains.

+ Sprint · + Reload

OP-06 · Anvil

Manny

Soaks hits the others can't. The body that holds the cade while the squad works.

+ Toughness

OP-09 · Medic

Quinn

Keeps the squad breathing — faster revives, better meds, more per bandage.

+ Revive · + Heal

??Sealed

OP-?? · Classified

Drongo

Personnel file sealed. Clearance granted to squads that reach the deep waves.

Unlock · Wave 20

File 05 — standing orders

Survive the wave. Spend the points. Come back stronger.

Fortify

Between waves, nail up cades, drop turrets, reinforce the choke points.

Hold

The horde escalates every round — runners, howlers, bloated, and worse.

Bank

Kills pay points. Loot corpses for brass, meds and gear to fill your bag.

Upgrade

Pack-a-Punch a weapon, buy a perk, unlock a door, push deeper into the lab.

Straight out of the editor

Real captures from the current build. Lighting, UI and the nuclear-lab arena are still being polished — this is the game as it plays today.

File 08 — field loadout

Four perks. Two skills. Your build.

A Dark-and-Darker-style loadout: slot four passive perks and two active abilities before the raid. Every perk is a real skill-tree node — earn it, equip it, feel it.

PERK · PASSIVE

Quick Hands

Reload, bandage, nail and loot all 18% faster. The tempo build everyone learns on.

+18% action speed

PERK · PASSIVE

Thick Skin

+40 to your max health pool. Soak the hit the others can't and hold the doorway.

+40 max HP

PERK · PASSIVE

Killer Instinct

Every round bites 15% deeper. Turns a good wave into a cleared one.

+15% weapon damage

PERK · PASSIVE

Ironclad

Barricades you nail gain an armor shield and more base HP — and the carpenter perk makes your nails hold longer. The wall holds because you built it.

+cade armor · +cade HP

SKILL · ACTIVE · [Q]

Adrenaline

A burst of +30% move speed and +25% action speed for 8 seconds. Kite the horde, revive a friend, run the train — then it's on cooldown while you earn it back.

8s burst · 45s cooldown

SKILL · ACTIVE · [E]

Overclock

Your turrets fire 40% faster with +25% range for 10 seconds and instantly repair 25%. Make the sentry line sing at the exact moment the wave breaks.

10s turret surge · 60s cooldown

File 09 — field medicine

Seven zones. Every one can fail.

Tarkov-grade vitals. Bleed out, fracture a leg, black out an arm — then patch the exact limb with the exact tool. Drag a med onto a body zone, or right-click to quick-use.

ZONE · CRITICAL

Head

35 HP. Black it out and you're down. Protect it with a helmet.

Pool35

ZONE · CORE

Thorax

85 HP. The engine room — losing it ends the run. Plate carrier goes here.

Pool85

ZONE · LIMB

Arms · Legs

60–65 HP each. Blacked limbs cost you aim and speed until you splint them.

Pool60/65

TOOL · MEDS

The kit

Bandage stops bleed. Tourniquet clamps the worst. Splint sets a fracture. Surgery restores HP. Painkillers push through.

Tools×5

SKILL · REGEN

Regeneration

Buy the Regen skill and it clears your bleeds and heals your limbs back over time — hands-free.

File 10 — hold the line

The wall is a weapon

Grab a crate, hammer it into the doorway, and it becomes a living part of the fight — with real health, armor, and a horde that adapts to tear it down.

01 · BUILD

Nail & Reinforce

Hammer nails into a prop, then spend points to rank it Wood → Reinforced → Metal. Watch the green HP bar and the steel armor bar climb.

HP bar · armor bar · 3 material tiers

02 · CHEW

The horde adapts

Zombies keep hammering the structure at 2–30 damage a hit, the wood heaving harder the closer it is to giving. The chew even climbs in pitch as it weakens.

2–30 dmg/hit · escalating siege

03 · BREACH

It gives — and moves

When the nails go, a player-placed prop breaks loose: zombies shove it, knock it back, and pour through the gap. Nothing about a broken cade is safe scenery.

breach · loose-prop knockback

04 · REWARD

Aim for heads, harden your walls

Every string of headshots you land pumps extra HP into the healthy barricades you nailed — and the Carpenter perk makes every nail you drive tougher. Offense literally feeds your defense.

headshots → +cade HP · Carpenter perk → sturdier nails

05 · SENTRIES

Turrets & traps hold with you

Drop auto, flame, tesla, cryo or rocket turrets from the arsenal crate, wire electric traps into the choke, and repair the line with your hammer between waves.

Patch notes

Fresh from the lab. The launcher pulls every one of these the next time you start.

v0.9.1 · SIEGE & STRUCTURES

The horde breaks through

Zombies now pour through a barricade the instant it's destroyed instead of grinding on dead wood, and they keep hammering structures at 2–30 damage a swing. Jump finally feels right — air control fixed — and you physically shove zombies now instead of clipping through them.

Breach-on-break · 2–30 dmg/hit · jump feel · push collisions

v0.9.0 · PAPER OVERHAUL

Torn-paper everything

A full survival-journal UI pass: reworked HUD strips, the LOADOUT grid, the FIELD NOTES skill tree, and a Dark-and-Darker-style perk & skill loadout — 4 passive perks + 2 active skills on cooldown. Drag-and-drop the grid bag; right-click your gear.

v0.8.x · SURVIVAL SYSTEMS

Vitals & economy

Seven-zone Tarkov vitals — bleed, fracture, tourniquet, surgery. Pack-a-Punch, 30 perks, buyable turrets, corpse looting and wall-buys.
