Yeah been playing that castle map, crazy map that is, at first thought it was going to be rubbish as a team can be pinned in, but then thought about the different classes and there are ways to get out of it and make the game work really well!
I am mainly downloading as i connectr just now, but obviously if we get a server or the 7th dr server will need them downloading onto the actual server machine I think.
ah lol. It seems the Source SDK for TF2 is not out yet and is going to be released on the 30th October. But some have found a way to get round this apparently. But once this SDK is out custom maps should start appearing a lot then.
