What this is

A first-person arena shooter. 2285 lines. A wide canyon map: rocky walls, two opposed bases (blue + red), buggy spawn points, central rock formation with weapon pickups, teleporters. Green powered-armor visible arms hold angular sci-fi weapons. Six weapons: precision sidearm (24 dmg × 2.6x headshot = 3-shot kill, the signature duel weapon), assault rifle, shotgun, sniper rifle (one-shot body), rocket launcher, plasma pistol with right-click charge for a shield-erasing 100-dmg overcharge. Energy shields (segmented cyan, recharge after 3s out of damage) + health (red, doesn't recharge). Frag grenades (G key, arc + bounce + 3s fuse). Melee (F, rifle butt). Buggy with drift physics — drive (WASD), gunner seat with chaingun. Motion tracker bottom-left (red dots = nearby enemies, ~30m range). Cyan angular HUD aesthetic. Choir + martial percussion music synthesized via FM-stacked sines through bandpass formant filters. 4 red-armor bots with wander/pursue/engage AI. Slayer mode: first to 25 kills wins.

Why this is mind-blowing

A full first-person arena shooter — canyon map, vehicles, AI bots, synthesized score — built faithfully from a single paragraph in 2285 lines. The precision sidearm still rules the canyon. The buggy still drifts. The motion tracker still tells you where the threat is. Open the demo, see the powered-armor arms, hear the choir kick in. You're in.
