They reveal Knights Contract which follows an immortal executioner and a resurrected mortal witch. They battle together to fight the supernatural.
The "resurrected witch" Gretchen gains control over her "immortal executioner" Heinrich, and they go off to battle the supernatural forces of Heinrich's old master Dr. Faust.
The player assumes the role of Heinrich and can dish out orders to the AI-controlled Gretchen, reports. The goal is to ensure Gretchen stays protected because she's mortal and therefore fragile.
Namco themselves note that "Heinrich can never be vanquished" but the witch's "mortality is the key to the duo's survival." ...there's always a catch for immortality.
Knights Contract releases for Xbox 360 and PS3 sometime in 2011. Does this magical action game sound like your kind of supernatural challenge?
