There are two difficulties to choose from for WoW TD 2: normal and hardcore. You can play the game cooperatively or by yourself. When you first enter the game, you choose the difficulty and what your tower builder is going to be. They range from a basic energy builder with no benefits up to an ArchAngel that can attack enemies as well as build units.
Most of the "towers" in the game are WoW-related units. Night Elf Archers, Orc Warriors, Goblin rogues are a few of your choices. The Night Elves are females that even have their bouncy idle animation.
