Microsoft's GameStock is firmly underway, and so they have relaunched Xbox.com with new information about the upcoming games for this console system (thanks MSXbox.com). The new site has new screenshots from Halo (which feature Bungie's redesigned graphics engine) as well as Nightcaster, a third person action game from VR-1 and six other titles. Look for more from GameStock this afternoon, including new shots from the PC titles Dungeon Siege and Sigma. More stuff (including extra Halo shots) can be found at the home of The Official Xbox Magazine (thanks Stomped).
