falling enemy traps are quite funny in multiplayer. You need a high room, enemy statues, timer(s) and active stone blocks. build roof out fo sight, make it allmost entirelu out of active stone, exept some spot, place statues on them wire it up to a preassure plate on the floor. When someone steps on it, ITS RAINING ENEMIES !!!
