Robot Entertainment will be bringing its just-announced Orcs Must Die! 2 to Boston, MA from April 6-8 for PAX East 2012, offering players their first opportunity to sample the newly added co-op feature. The announcement press release touts a number of other elements as well, such as a more flexible spellbook, a new upgrade system, and an all-new campaign set after the events of the first game.
The Orcs Must Die! 2 campaign will be fully playable in single player as well as in co-op, with players stepping into the shoes of either the War Mage or the newly added Sorceress, who specializes in mind control and magic. The game's official website mentions a summer 2012 release for PC, though a tweet from Major Nelson on the announcement (not to mention the previous game's XBLA release) strongly suggests that the sequel is coming to XBLA as well.
