What kind of beast Q1K3 Shooter is: rules, tricks and a few tips

The igrasu.ru catalog holds hundreds of games, and this is one people keep coming back to. Here is how it works and how to get the most out of it.

What this game is

Q1K3 (Slaughter in the Bunker) — a retro first-person shooter on a hand-made raycaster engine, built for the 2021 js13k competition. "Quake" in 13 kilobytes: a custom WebGL renderer with no third-party libraries, dynamic lighting, 30 procedural textures and Sonant-X synthesized sound and music — not a single external asset, everything is computed by code (maps compiled from TrenchBroom, models from .obj). Two levels of a hellish base, five enemy types (zombies, hounds, grunts, enforcers, ogres), three weapons — a shotgun, a nailgun and a grenade launcher — plus keys and doors. Enemy AI runs line-of-sight checks and gives chase; the collision handling copes with fast-moving projectiles. Controls: WASD or arrow keys to move, left mouse button to fire, space or the right button to jump, Q/E or the mouse wheel to switch weapons; the cursor is grabbed full-screen. On touch devices: an on-screen movement pad, a drag-anywhere look zone and FIRE / JUMP / GUN buttons. WebGL required.
