Halo is an award-winning first-person sci-fi shooter made by Bungie Studios and Microsoft. First released for the Xbox, the game has been ported to the PC and MAC. With jaw-dropping graphics and sound, wonderfully-meshed gameplay, intuitive controls, and an impressive attention to detail, Halo is a very popular game with quite a bit of staying power. The highly anticipated Halo2 is expected to be released for the Xbox in 2004.
