The two levels available for demo at the 2009 E3 Expo included remakes of Level 2 (Alley Cat Blues) and Level 5 (Skull and Crossbones).
Alley Cat Blues is in a modern Manhattan Alley with Foot Soldiers and mutant baddies to battle. Enemies will try to fling manhole covers at you, and while these heavy disks can hurt, you can also deflect them back at the baddies by timing a weapon strike at just the right moment. Once the manhole lids are gone, watch your step or you'll fall into the open hole.
Skull and Crossbones takes place in the year 1530 A.D. with the Turtles trapped on a pirate ship, battling (you guessed it) Foot Soldiers, Stone Warriors and Robots.
