This is the prototype of Quake for Game Boy Advance made by Randy Linden in 2002. Upon booting the game, we can instantly see how impressive this demo is for the hardware, with its capabilities effectively managing to outshine just about every 3D game out there that was released for the system. Not only that, it feels exactly like a Quake game. From the guns to the environments. You can even dive underwater! The game is fully 3D rendered, rather than the ray casting method most GBA games are known for. It has 3D enemies, animations, and point lighting effects (even on pre-rendered objects like weapons, which use a clever palette-changing trick to achieve the illusion of dynamic lighting). The camera and movement work is equally as incredible; it travels very cleanly, as opposed to being jittery.
