Splatterhouse

To splat an enemy on the wall, simply use a weapon such as the lead pipe or 2x4 and attack an enemy near a wall. You should send them flying into the wall. This is easy in Survival mode where you have weapons raining from the sky, just stay near the outer edges near a wall and you should be able to get this easily. Also, using Pimp Hand Strong (RT+X) while holding a weapon will send enemies flying into the wall almost every time. I've found this to be especially effective on side scrolling sections where you have weapons available. The only weapons that this doesn't work for are the Shotgun and Machete.
