## About

SuperTuxKart is an open-source 3D arcade kart racer starring Tux the Linux penguin, Konqi, Kiki, Suzanne, Pidgin, Gnu, and a full roster of open-source mascots. Originating in 2000 as TuxKart and reborn as SuperTuxKart in 2006 through the Game of the Month community initiative, the project has spent two decades evolving its custom Antarctica 3D engine across desktop and mobile platforms.

Powerslide around volcanic islands, Scottish castles, dusty haciendas, snowy mountain passes, Cocoa Temple ruins, and underwater research domes. Skim zipper pads, chain three-stage drift boosts, collect nitro cans, and trade bowling balls, plungers, bubblegums, swatters, and homing cakes across 8-kart fields.

Key Features:
• 21 handcrafted tracks and arenas streamed seamlessly on demand via incremental WebAssembly asset packs.
• Full Story Mode (Overworld adventure against Nolok), Grand Prix cups, Single Race, Time Trial, Follow the Leader, 3-Strikes Battle, and Soccer Mode.
• Custom Antarctica 3D renderer running on WebGL 2 with dynamic lighting, particle effects, and four AI difficulty tiers (Novice, Intermediate, Expert, SuperTux).
• Three kart weight classes (Light, Medium, Heavy) with distinct acceleration, top speed, and drift handling.
