How long ago was this? Valve just released a patch fixing pretty much all glitches. I've never heard of it though... I don't think anyone can purposely get stuch outside of the door.

DLC has been announced for Spring. We're getting a new game mode, the new game mode will have over ten levels (or something along those lines), and Dead Air and Death Toll will now be playable in Versus. I don't think we're getting new maps for campaign though. It would be nice, but I haven't heard anything about it yet.

DLC is downloadable content, basically in the spring new stuff will come out for the game, like the other 2 campaigns for versus. I'm not sure if there will be a new campaign, but it'd be pretty cool if there was

I've seen people quickly close and then reopen the door tot the safe house and all. (even though on versus specifcally this is done, that when they reopen it it already registered everyone inside so the door is wide open but the points are going.) Don't think I've ever seen it happen on a campaign with someone stuck outside though. And I've done tons of games. lol

I'd like to see it. >.> XD
