Just up on Xbox LIVE this week is the first volley in the latest onslaught of Warhammer 40k branded games, Kill Team. Revolving around an Orc assault on an Imperial Forge World, Kill Team casts players as Space Marines in either single or co-op action.
One of the coolest things about the game is that completing just the first portion of it unlocks the chain sword in THQ's full retail release, Warhammer 40k: Space Marine. That game releases next month, but in the meantime there's no reason not to pick up the demo version of Kill Team and give it a shot.
The game actually looks like a solid shooter, and if you do decide to bump yourself up to the full version, it'll only cost you 800mspts. Not too bad.
