If there are any games fit to serve as killing grounds for millions of orcs, it's Warhammer 40K: Space Marines. THQ and Relic have put out the E3 2011 Chaos reveal trailer and there is plenty of orc blood with which to spice your dinner.
Space Marine puts you in the shoes of the ultimate weapon. Literally a walking tank, you are a Space Marine tasked with defending a Forge world from an invading horde of orcs. See all the action in the trailer below.
Space Marine is set for a release this Summer on PS3, XBox 360, PC.
