I think its also part of ur ip tho lol

DMZ was a game mode in mw2 that was an open world-ish one-life pvp/pve that amassed a large community but was removed and has had no mentions since :(
If you want to see gameplay/tutorials I recommend the Yh channels Westie, Stodeh and Phixate

Yoooo DMZ???

What's tsp?

Look at daddy’s glowing reviews on yelp:
