Lol I love doing that. Lately I've been trying to do it in left 4 dead but it's pretty difficult. The enemy teams typically shoot you on sight so I've only ever don't it once. I was a jockey and jumped into the safe room just before they shut the door. I ran they started shooting at me but stop once they seen I wasn't attacking. We just sat in the safe room chilling while my teammates were asking why weren't they killing me. Fortunately the game won't end if there's a zombie in the safe room with the survivors.[spoiler]also soul mates sounds kinda gay lol[/spoiler]
