Played it with 2 friends yesterday and I think it was awesome. Dark Zone is really interesting and we had some nice encounters.
People trying to shoot one friend while we were extracting and not noticing us taking cover. So they tried to steal our loot but ended in being taken away theirs
The city is just beautiful, so much to see and explore. Beginning was great, when you come into that starting zone with other players. Too bad once you leave that area you're alone on the map (except for your squad and of course the Dark Zone). But you still can see your friends on the minimap even if their not in your squad.
Loot was a bit weird. I found only one weapon (level 7) so far that's slightly better than the level 4 starting MP5. And I did buy a blue level 7 AK47 that was a bit better than my starting M4. The rest of the loot was (way) worse than the starting weapons, even higher level blue stuff...
We've been playing over 4 hours and it feels like we just scratched the surface.
