The DMZ is absolutely fantastic. Such a great game mode to chill on and i'd say the only downfall is we can't group up with more players on it. The AI is quite hard in places which really adds to the difficulty and the PvE missions just keep making you want to go back in for more stuff. Outside of that, you then can be sidetracked midway through a run because something will happen in a part of the map, which is really great to add to the unpredictability of each try. We had a run the other night with @James5497 and @MrBiron when a Weapon Case got picked up and marked it on the map. We decided to change plans and take the armoured truck we just dropped off for a bounty and it was a race against time. Just got there with the Helicopter down to extract, we ran them over and shot them clean out. Picked up the case, extracted and got 'Caution Tape' Weapon Blueprint!
Honestly, when you have 2 or 3 of you and waiting for others to come, this is the gamemode to have a few go's on. So many others enjoy it too here.
