According to Robot Entertainment, only 3.5 million orcs have been massacred since Orcs Must Die! was first released. This, apparently, is unacceptable. To rectify the situation, Robot Entertainment has announced this morning that they will be releasing Orcs Must Die! 2.

In order for the slaughter fest to be even more productive, they've added co-op mode, and a new character. In addition to the original War Mage, a Sorceress has been added to amp up the kill count. As always, there will be other updates, including new campaigns, enemies, and upgrades, to name a few.

If you're going to PAX East, so is Orcs Must Die! 2, so check it out. In the meantime, the trailer is below. The music is pretty snazzy, I must say.
