OpenXCOM: XCOM

AmiXcom is a native AmigaOS 3.x port of OpenXcom — the open source reimplementation of X-COM: UFO Defense and X-COM: Terror from the Deep — for real classic hardware: 68020+ without FPU, AGA chipset. Not PiStorm-, Vampire- or Emu68-only. No SDL: the SDL 1.2 API the game expects is a small shim (native/sdlmini/) on top of a bare-metal Amiga graphics/audio layer.
