Orcs Must Die! 2 launches on 30th July 2012, Robot Entertainment has announced.
The PC action strategy game features a new single-player and co-op campaign, more enemies, more defences and a new upgrade system.
The story begins right after the ending of the first game, and sees the War Mage fighting off against more orcs. He has a new companion, the Sorceress, an ex-War Mage who destroyed the Order. You can play the campaign as either the War Mage or the Sorceress, who uses mind-control and magic.
If you have the first game on PC you will unlock exclusive content in the sequel, Robot said.
