Why I built it

Most shooters forget everything when you die. I wanted a war that keeps going without you – where the rifle on your back is actually yours to lose.

-Your gear, your risk. Go in with a free standard kit, or with gear you bought and looted. Die, and it stays on your body for whoever gets there first.
-Get home, get paid. Walk out, drive out, or call a heavily armed helicopter – it isn't cheap.
-Every wall is a decision. Shoot through it, breach it, or bring the whole building down.

The AI actually communicates

This is the part I'm most proud of. The AI only knows what someone saw, heard or reported – no wallhacks.

• Tank on the street? The squad calls it out, the leader radios type, position and heading. Other squads re-route around that street – or send their anti-tank gunner to the flank while the rest keeps it busy. Riflemen don't waste magazines on armor.
• You drop three of them from a window? The rest takes cover, estimates where the shots came from and stops walking into the same spot. If a whole squad goes silent, command notices and marks the area as a kill zone.
• Clearing a house: covering fire → grenade → two-man entry → "room clear" only once the corners have actually been seen. A quiet enemy behind furniture can still surprise them.
• Out in the open: one team covers, the other bounds from cover to cover. Nobody crosses open ground without someone watching their back.

Simulated like the real thing

-Ballistics: muzzle velocity, drag per caliber, bullet drop, penetration through walls and armor plates.
-Organs, not hit points: brain = instant, heart = a few seconds, lungs = bleeding and gasping. Plates only protect what real plates cover.
-Field medicine: tourniquets, pressure bandages, splints – with first-person animations.
-Sound: real recordings only, with distance, echo and the delayed boom of far-away shots.

What's in the alpha

Under the hood

• Godot 4.7 – gameplay in GDScript, the heavy lifting (voxels, navigation, movement, poses) in C++ via GDExtension.
• Signed delta updates: the game checks for new builds, downloads only changed files and verifies the signature before installing. Updates ship several times a day.
• Automated QA: before every release a test pass checks the UI and the world for things like floating trees, clipped buttons and overlapping text.

Play it in 60 seconds

1. Download ATTRITION-Windows.zip
2. Right-click → Extract All
3. Start ATTRITION.exe – if Windows says "Windows protected your PC", click More info → Run anyway (not code-signed yet)

Heads-up: it's an early alpha, so expect bugs. The game text is German for now – English is coming, and the menus are short and easy to use.
