(adsbygoogle = window.adsbygoogle || []).push({}); Edit #2: According to several n4g members, these maps are already released. This is a quote from a reply in the thread:
"NIGHTSHIFT IS SKIDROW
BRECOURT IS THE NAME OF Wasteland back in Call of Duty 1

Boneyard is Scrapyard
Checkpoint is Karachi

Yourwelcome..lol they are released"

lets hope he's wrong

I was in my linux on my ps3 and i came across the file manager. I opened it up, and what do you know, there were all the files for the inserted disc. I quickly started checking all of the files kept on the MW2 disc (this is on PS3 by the way), and i found four new maps named "mp_boneyard.ff", "mp_brecourt.ff", "mp_checkpoint.ff", and "mp_nightshift.ff" (also the corresponding mp_*****_load.ff for each)
Thought it was pretty cool so i wanted to share on n4g.

*Edit: I would upload the files, but in total they are 660.4 MB You must login or register to view this content.

Yes lets all repeat what the guy just said above us...

On COD4 there were alot of maps saved on the disc that weren't in use, but were there because they got cancelled from the game so maybe it's a similar situation with these?

Easy way to sort this actually how many maps are currently in the game? And how many files are there? If there the same then theres no new maps
