Posted March 1, 200817 yr This may be common knowledge. We just found it now and its alot of fun. Get 2 engineers (Yourself and a Friend) It is possible to do by yourself but nobody would fall for it. Actually they might.. Find an hill or ramp or staircase in the terrain and put a teleporter exit on the bottom of the incline whichever you chose. Then right on top of that exit have a friend put another Exit. They should look almost stacked ontop of eachother. Everyone that takes that teleporter will be stuck on the exit. Alternatively you can have the entrance of your teleporter ontop of your own exit.
