The Plagued Gamer says: "Entering the overflowing tower defense genre, last year's Orcs Must Die! was a breath of fresh air. Fast forward nine-months later and Robot Entertainment has improved its Orc murder-simulator tenfold. Adding a host of new traps, weapons and the much sought after co-op mode, Orcs Must Die! 2 is a perfect representation of how a different take on a familiar genre can reinvigorate even the most worn out trends. More importantly, from start to finish it's just a damn good time."
