Ironhammers writes: The first Orcs Must Die! came kind of out of nowhere when Robot Entertainment released it last October. I reviewed it myself, scoring it a rather prestigious five-out-of-five. I praised not only its gameplay, but also just how well-made the PC version was. So, with Orcs Must Die! 2 bringing more of everything the first had, as well as being PC exclusive this time around, does it retain its place as a must-buy game?
