Orcs Must Die 2 Release Date

For those unfamiliar with the game, Orcs Must Die was a great Tower Defence game that saw you pitted with an arsenal of magic and deadly traps against a horde of invading orcs. You can read my review on the game here.

Robot Entertainment has now announced a sequel which will be released on the 30th of July 2012.
The sequel will bring more of the same and most importantly: Added co-op!

The released pictures so far look great, Especially of note is the below picture set outdoors. Could this indicate more open areas for warfare? It would definitely add a lot more challenge to the maps, even with co-op in mind.
