Bungie has released some technical information about the upcoming Halo 2 port for PC. While it will require Windows Vista, it will not be needed for player to have a DirectX 10 compatible gfx card, as Halo 2 will work on DX9 boards as well. PC and Xbox gamers will not be able to play against each other, as Bungie thinks the two-year time frame between launches would be too big and not level the playing field. It will also pose a technical problem, as the PC version will have exclusive maps, and a map editor allowing the mod community to make their own material.
