From the June 2008 PC Gamer (US), there are some more screens and some juicy bits:
- all races will be playable in the campaign
- for SM, you'll play through the campaign with the same set of squads with unique sargeants with their own VA work and abilities, etc. You can upgrade squads with wargear earned in missions by doing quest-like objectives and from killing tons of enemies for added customization.
- building garrisoning ala COH is in. Shows a screen of Ork Shoota Boyz fighting out the windows of a building.
- multiplayer mode is still hush hush, as is squad reinforcement details
- coh styled cover is apparently in
Worth getting the mag to see the screens IMO. Really impressive stuff.
