# OpenBreed: reconstructing the classic Alien Breed games

> OpenBreed investigates and reimplements Alien Breed Special Edition 92, Alien Breed II and Alien Breed: Tower Assault. Its C# editor reads maps, sprites, tiles and image formats from original resources, while the author works to recover behavior and tables stored in the games' executables. The game engine lacks game-specific logic and is not yet playable.
