this is a pretty good map, but if you jump into the teleporters you die, i think that's a bit unessasary, because i was in a firefight with someone and accidentaly jumped backwards into the death telelporter, you should have those teleporters on the otherside of the wall, or just make them telleport youto the base of the wall.
This made me think: It is going to be easy to break. It also seems as if most of the wall that goes across the bridge (original power drain spawn) could be pushed. I do like the idea though, Ill give you props on making a map with virtually nothing to work with.
