Orcs Must Die 2 will be released for PC on July 30, developer Robot Entertainment has announced.

The tower-defence-ish sequel picks up immediately after the first game, which I found by way of Steam's Christmas sale last year and ended up having an awful lot of fun with.

Orcs Must Die 2's biggest new addition is the Sorceress, who can be used in either single-player or in co-op alongside the returning War Mage hero.

There's also a redesigned skull system, alongside plenty of new orcs to kill and ways to kill them.

Owners of the first game are promised some exclusive content in the sequel, too.
