I've decided to "convert" MW3 DLC maps as usermaps since a lot of players seem to be lazy to download them. I'm sure it will be very useful for server owners, no need to worry about players having them installed or not

This map is kinda special and is not really meant to be played for objective gamemodes, I won't bother adding them. Demolition, Sabotage, Search and Destroy, HQ, Capture the Flag and Drop Zone are not supported.
Same goes for the killstreaks, the map is all inside an office, so most of killstreaks are not supported.
There's a minor visual issue on some jump pads that I didn't manage to fix, do not report it.

@hindercanrun @RedxSkull https://www.youtube.com/watch?v=F_f7mm4NmvM here's a video of what the map looks like on the original game. I think it was only made for that gamemode, but of course we don't have that on MW3
