Halo 2 is coming to the PC, but…you won’t be able to play, until Vista comes out. Because Halo 2 will require the upcoming Windows Vista operating system to play, but it doesn’t require a DirectX 10 card. Also, the PC version will not be able to play with the Xbox version because the PC version will have new maps and a map editor. Halo 2 PC will lose the clan playlist feature from the Xbox version. But with a twist. Clans still function, but players will no longer have a clan rank.
