3D Tomb II : The tomb of the 4096 mummies
3D TOMB II is a first person shooter in a fully textured environment done in less than 4KB of JavaScript. It was initially made for the5k 2002. Unfortunately the contest got cancelled so I waited for an opportunity to release it while adding more features and optimizing the game beyond all my expectations.

Technical feat
3D Tomb II is a fully fledged game in less than 4KB ( 4096 bytes ) of DHTML. It features multiple levels, enemies, items, HUD, textures, high scores, … Including all assets ( images, style, markup and JavaScript ), 3D Tomb II is actually 4003 bytes big.
A total of 144 textures are generated based on 6 base textures, 3 tone maps and 8 mathematical patterns.
To render not only the walls but also the floor and ceiling in a size efficient manner, floorcasting was favored over the traditional 2 passes rayscating approach. Using mirroring and time coherence between frames allowed for a frame rate of 10-15fps in Internet Explorer, back in 2002.
The controls
Use the arrow keys to move and turn around, x and c to strafe left and right, and space to shoot.
