Which is the best level to get this acheivement? I tried Darth Maul, and throwing a TD at the droids at the very top of the walkway section before heading to the energy room, but no luck. Anyone have a better level to get a bunch of characters together?
Episode 4, escape from the Death Star. At one point in the level some doors open in front of you and you are confronted with about 15-20 stormtroopers... play the level, you'll know it when you see it.
