[1UP] As we predicted with our last post on Halo: Reach, the flow of information on Bungie's final Halo game -- well, the beta, anyway -- has now become steady and consistent. Today's exclusive preview of the beta's new multiplayer game types (read: not CTF/Slayer/etc.) at 1UP is further evidence of just such a trend, detailing the Headhunter, Invasion, Stockpile and Generator Defense (quaintly dubbed "Network Test 1 Beta" by Bungie internally) multiplayer modes. Read on after the break for all the details.
