Teleporters send you to a small prison for 45 seconds, where your enemies can take potshots at you.
Three levels, all open. One small bug, but other than that, a pretty cool example of bridging.
A big collection. Well-made, but they all start to look alike after awhile. Most are pretty big (4 players plus).
3 more from the CarnageMeister. 2 originals, one modified Bungie level (Ingue Ferroque). Much better than the last batch (IMHO). Mars' Canals is deadly!
