GamersMark: "It's not too often you get to be the bad guy in a game. In Overlord: Raising Hell, you're given the primary role of being "The Overlord" - the master of the Minions. With their help, you'll rebuild your evil kingdom, confronting those that have killed your predecessor and rebuilding your once-fear-inducing-yet-humble abode. Throughout the levels you'll find pieces of your tower, power-ups, and more minions to help you.
Essentially, Overlord is a mish-mash of a few genres - action, RPG, and real-time-strategy. The action influences come from the obvious gameplay mechanics such as controlling a menacing dude who goes around beating people with his axe, solving puzzles, and the like. The RPG elements come in with increasing your stats by gaining new weapons and getting new power-ups to help you maintain those stats. The most interesting aspect of Overlord, however, is how it accomplishes being real-time-strategy in tandem with the aforementioned aspects of gameplay."
