Bungie's first sci-fi trilogy released for free
A free, open-source version of Halo developer Bungie's classic Marathon trilogy has been released online. Available for Linux, Mac and PC, the pack contains an updated version of the engine, a fan remake of the first Marathon, and lovingly HD remastered versions of Marathon 2 and Marathon Infinity. The new versions sport modern features like online multiplayer including co-op; control pad support; and OpenGL shader functionality. You can grab the pack here. The Marathon series of shooters kicked off in 1994 and wrapped up in 1996, predating Halo by five years.
Thanks, Shack.
