This is from the new demo Darkest of Days by 8monkey labs. It's based off of the Marmoset engine which I hadn't heard of previously. It sacrifices a bit on the graphics but allows for hundreds of NPC's to be in the vicinity at the same time for some intense combat. The concept of the game is to allow you to run through some extremely historic battles but with the option of using the weapons of the past or some more modern weapons. This game is single player only. I did find it be a good first effort although I worry about replayability. (less info)
