The record it targets
That green sliver is the whole game. It is about 19 times smaller than the current Guinness World Record for the fewest bytes in a first-person shooter, and smaller than the average email signature.
What is in there
A real level of rooms and corridors, perspective floor casting with a tiled ground, brick-textured distance-shaded walls, and mouse look. Drawn a column at a time.
Zombies spawn in the far rooms and path through the corridors to find you via a flood-fill distance field. Brutes fire dodgeable projectiles from range, and red edge markers grow as off-screen threats approach.
Pistol, shotgun, and SMG, each with its own fire rate, damage, sound, magazine, reload, and gun. A top-left readout shows the weapon and live ammo count. Plus fog-shaded enemies, recoil, blood, and endless waves.
The sine and cosine tables, the map, and the color palette are all generated at startup, so almost none of it costs a single byte on disk.
