http://www.turrino.it/public/fortress-trick.sdm hmmmpft. i dunno if anyone noticed before but that thing can be quite useful for pissing the flag away from position.
hey you should have made the demo in the game you discovered it so I'd be on it ;D
well I think its a bug because you hear the grenade bouncing mad around and get up..
hmm. i think the map creator made it like that on purpose, because of the special structure of polygons there. or it might be because the dumb map maker only makes triangle polygons. :O
i think it's wanted that this is possible. Because, why should this hole be there for no reason, it doesn't even look good. So I think it's a trick, possible by a bug ;)
