Open-source reimplementation of the original UFO: Enemy Unknown (X-Com: UFO Defense in USA), licensed under the GPL and written in C++ / SDL. The goal of the project is to bring back the tried and true feel of the original with none of the issues. All the same graphics, sound and gameplay with a brand new codebase written from scratch. This should give it: * Fixability: Play the game natively without any need for emulators or fancy hacks, with none of the limitations and bugs that plagued the original. * Moddability: Tweak the game as you want. Sure the original was good, but maybe you think it could be that bit better or challenging. * Flexibility: Port the game to any platform, customize it to your liking, or use it to make your own far-fetched remakes.
