Those grey things you see are fence walls. The shotgun is sitting in between the outer two, making it look like a shotgun "slot." The red thing is an OS. lol.
OMG it Creep! This map is awesome. 4.8/5 Plays great. The only reason it's not a five is because the 1st Floor middle is an extreme choke point. It's like the opening seconds in the rocket hall on the Pit only all game long. And maybe a little much grenades on map. Still incredible, though.
Yeah, thanks. It's got a lot of power weapons and grenades, I agree. Probably not something to suddenly change for a new v3.
