Warhammer 40k: Squad Command preview at Gamespy.

"Warhammer 40K: Squad Command was available for a quick peek at this year's E3, giving us the mixed blessing of being excited for a title we don't have nearly enough information on. Releasing on both the PSP and the DS, with graphical glamour and ease of control anchoring the respective platforms, Squad Command puts you in charge of small-scale Warhammer 40K combat as a Space Marine leader in single-player, and as either a Space Marine or Traitor Legion (Chaos Marines, if you must) leader in multi-player."
