Details: Discover how corruptible you are in Overlord, the twisted fantasy action adventure where you can be evil (or really evil). In the game's seriously warped fantasy world, players will become the Overlord and get first-hand experience of how absolute power corrupts absolutely. You could be a regular run-of-the-mill Overlord. However, with incredible power at your disposal and a team of evil-minded impish critters, the Minions, on hand to do your bidding, how will you resist the temptation to be wonderfully despotic?! The Overlord has the power of concentrated badness right from the start and you'll know how much more of a total bad-ass you're becoming as the game tracks your 'corruption' throughout. How corrupt you become depends on how you handle any given situation, your actions and how their consequences impact the game world.
