Enemy Smackdown is a fun Arena-style level type. Basically, you spawn in a particular area, and walls come up around you. Your character will enter their battle pose as a set number of enemies begin spawning. A counter with the face of a Batreon on it will pop up, telling you how many enemies are left. You battle the swarms of enemies until the counter goes to zero. Once the counter is at zero, the walls go down and you win.
