Welcome to Beast Mode

Survive all 12 waves of Beast mode (any difficulty, any map).  

Beast Mode tasks you with using the Locust enemies to kill groups of Stranded and COG. It is basically a reverse of Horde mode. You need to eliminate every enemy before the time runs out, though kills will earn you more time (starting with one minute) as well as money to purchase better characters. You can do this on Casual for the easiest go of it.
