Downtown Barrel Beatdown15
Kill 10 aliens with tossed objects
In The Duke Cave, you learn how to throw to throw objects at enemies. Dispatch the first enemy and then proceed into the next room. Throw objects from this room at the two aliens to bring your total up to 3. Revert to checkpoint until you hit the ten total kills - you may have to resort to mêlée with the two together if overwhelmed.
