We've pulled all the screenshots from Microsoft's GameStock FTP site, and so we're pleased to be able to offer you local, high-resolution copies of them all. Here are new screenshots galore from Halo (including the ones released earlier today in a lower resolution), MechCommander 2 and Dungeon Siege, and we've also got some new character renders from Sigma: The Adventures of Rex Chance (as it is apparently called now).
