Summary: Orcs must die takes on a different style of tower defense. Instead of the usual "God" overview where you can place towers wherever you want, OMD is more of a mixture between a third person shooter and a tower defense.
Summary: Great graphics, its like a first person Torchlight, great sound, good options for configuring. Y invert, awesome mouse sensitivity settings. I'm about 5-6 hrs into the game so far. This is not your typical tower defense game where you are "safe" each wave.
