Enter a world where humans and creatures called Timenoids coexist. These blue-skinned Timenoids are determined to wipe out the inferior human race, and this is where you come in. You play the role of Millennia, a young woman who was brainwashed at an early age to do the Timenoids' bidding. She now believes that the humans must be exterminated from the world, which is rather ironic, since she is human herself. Yet if she succeeds, the Timenoids have promised her immortality and the power to become one of their own...

In this sequel to Tecmo's Deception, you are once again placed inside a castle to lure invaders into various traps. The game differs from the original in several ways, however. The view is no longer first-person, so you can see your character at all times. Multiple traps can also be triggered at once (up to three), forming even deadlier combinations than the original. In addition, the vibration mode is supported on the Dual Shock Analog Controller to provide feedback on each gruesome death. Prepare for a non-linear journey as the decisions you make during the game affect the type of ending you'll receive. Maybe, just maybe, you'll remember your past...
