THQ today announced that Warhammer 40,000: Space Marine, its upcoming 3rd Person Shooter, will be coming to the PC platform as well as Xbox 360 and PS3.

Jonathan Dowdeswell, General Manager of Relic Entertainment said that “The loyal PC audience is incredibly important to us here at Relic so we are delighted to be able to announce the PC version of the game.”

Space Marine “puts players into the boots of one of humanity’s elite soldiers, genetically engineered and equipped with state of the art weapons and armor. Players are dropped right into the action as they battle to defend an Imperial Forge World, from an invasion by the savage and brutal Orks, using the most devastating weaponry mankind has at its disposal.”

If it’s anywhere near as good as the Dawn of War games, also by Relic, then we’re due a really good 3rd person shooter. It’s great to see developers and publishers noting the PC as a worthwhile platform. I’ve a sneaking suspicion that it’s something to do with services like Steam bringing new and old players of Warhammer 40,000 to these games.

Space Marine will be released worldwide for Xbox 360, PlayStation 3 and PC in early 2011.
