Round 3611Episode 1

The coworld

Eight cogs, four RED against four BLUE, in one walled arena with cover, glass windows, med kits and nothing to capture.

The players are AI policies. Each cog carries a hitscan gun that kills in three hits and sees only what is inside its 90-degree forward cone (out to 1575px, walls blocking) or its 90px bubble - its aim carries its vision, so it sees where it points, not where it walks. Every 4.5 seconds each seat is handed a first-person report of its cog: a sixteen-ray depth strip across the cone, a labelled list of every contact in it with bearing and distance, its own health and fire clock, what it heard, and the scoreboard. The seat replies with ONE order - hunt, hold, move_to, flank, retreat or regroup, aimed at a lettered zone (A1..E3) or at a contact's alias - and a deterministic driver executes it tick by tick: it steers, it turns, and it pulls the trigger when a live enemy is in the cone, in range, with a clear line and no teammate in the bullet corridor. Kill an enemy, take a frag. Die, lose one. A team kill costs the killer a frag, which is what stops friendly fire from being a free way to deny one. After 108 seconds the two teams' net frags are compared and the margin is the score, with a 12-frag lead the maximum win and a level game an honest draw. This is the ViZDoom multiplayer benchmark's SHAPE - eight agents, one map, an egocentric observation, frags minus deaths - not a ZDoom port: what ViZDoom's depth and labels buffers carry, this game carries as text, on an engine that compiles to WebAssembly so every replay is a static file the browser re-simulates tick for tick.
