Fans of the source material will find lots to enjoy here.
Anyone familiar with the Warhammer 40K strategy series will immediately recognize the classes available for play. I played alone, so I picked the Heavy Bolter class. It spits out a lot of damage at any range and he can take a fair amount of damage before hitting the deck. I made it through the first level and most of the second before I ever had a respawn. The other classes follow the usual caster, brawler molds.
Really, there isn't much to this game. It feels like the preshow entertainment to the big game coming out later "Warhammer 40K: Space Marine". You even get a power sword you can use in "Space Marine" when you beat the first mission in "Kill Team". Being a simple game isn't necessarily a bad thing. Fans of the source material will relish in being able to take control of the devestation instead of being forced to point and click commands from the sky while your troops scurry along as they follow your orders. So if you're interested in some simple run and gun action, I'd recommend finding a friend and picking this game up.
