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. All 45 weapons take the ladder, standard arsenal included.
45 weapons · 3 PaP tiers

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

Nail It Down
Press G, 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 — and a four-tab stash to bank what you extract. (This whole page is styled after that in-game paper HUD.)
Grid bag · 7 gear slots · limb health · 4-tab stash
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. Eight emplacements, each with its own report, tracer and muzzle signature, so your ears can read the line.
MG · Shotgun · Tesla · Rocket · Flame · Heavy Cannon · Scorcher · Suppressor

Hired Hands
Buy a Soldier to hold a lane, an Upkeeper to patch the cades, a Drone to watch the sky. Real bodies with overhead health bars and a ten-verb order menu.

Pack-a-Punch it.
Three tiers on every gun in the game — ×1.15, ×1.3, ×1.5 damage at 4,000 / 8,000 / 14,000 points. 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.

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.

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

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

Seven zones. Every one can fail.
Tarkov-grade vitals. Spring a bleed and a countdown starts, fracture a leg, black out an arm — then patch the exact limb with the exact tool, channel bar and all. Drag a med onto a body zone, or right-click to quick-use.

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 → Steel → Diamond. Watch the green HP bar and the steel armor bar climb.
HP bar · armor bar · 5 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 MG, shotgun, tesla, rocket or flame turrets from the arsenal crate — or spring for the heavy cannon, the Scorcher or the Suppressor — wire 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 — the full patch log has the whole story.
LATEST · v0.2.5 · FRONT DOOR
A launcher that tells you the truth
The SVERA field launcher installs once and keeps the game current — real byte counts on the download, every one of the 4,326 files named as it unpacks, and the latest dispatch on the front page. Plus: the server list finally backs out on Esc or B, hosting caps at 20 instead of 4, and the in-game browser can see the internet at last.
launcher · auto-update · 20-player host · server browser · read the dispatch
v0.2.4 · SHIPPED HANDS
The build that ships All Hands Below
Everything from the 0.2.3 dispatch, downloadable now — plus full Xbox controller support end to end, true-first-person legs, third-person lean, a third-person aim fix, photographed shop portraits for every weapon, HUD toggle options, and Pack-a-Punch for the standard arsenal.
controller · TFP legs · aim fix · portraits · PaP · read the dispatch
v0.2.3 · ALL HANDS BELOW
New map: a submarine called Bellows
Multi-deck hallways, hull quakes that chip your health, leaks that flood the bilge with real rising water, and a crew-only elevator — the dead take the stairs. Plus three new turrets, the FAL, SV-98 and RPG-7, a Tarkov-feel handling pass with Q/E lean, and a squad you can finally see.
Bellows · 3 turrets · 3 guns · lean-peek · read the dispatch
v0.1.9 · THE HORDE LEARNS TO KNOCK
Your barricades finally matter
Regular zombies now attack barricades — the common horde swings at whatever blocks it instead of standing arms-out at dead wood. Big cades are reachable, props underfoot count, and the free arsenal crate stops spawning in your face.
cade combat · crate placement · read the dispatch
v0.9.5 · FULL ROSTER
The arms and the horde come back
First-person arms and all eleven special zombies are back in the packaged build — both were missing from the download before. Waves now genuinely scale as they climb, the mystery box pays out instead of jamming, corpse-loot rarity is fixed, and match XP is counted once.
FP arms · 11 specials · wave scaling · mystery box · loot rarity · XP
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.
HUD · loadout · skill tree · perk loadout
v0.8.x · SURVIVAL SYSTEMS
Vitals & economy
Seven-zone Tarkov vitals — bleed, fracture, tourniquet, surgery. Pack-a-Punch, a wall of perks, buyable turrets, corpse looting and wall-buys.
