Mostly impressed.
It's an unusual mix of Destiny and Watch_Dogs - which is surprising, since this has nothing to do with the studio that made that. Like, it may as well be Watch_Dogs 2 when you're on your own, wandering around NYC completing side quests, viewing echoes and killing low level mobs in random encounters. Then it transitions smootly with a short load for matchmaking in to a full on Destiny Strike at the MSG Medical Center - even down to the grinding it on hard for better loot just like Sepiks prime hard mode in Destiny Beta!
It works well, and it suggests there are 30(?!) of these "strikes"? (3 wings * 10 missions) If so, that's epic - and the levelling / loot grind hook loop is rock solid. I am much happier now I've obtained a solid blue Marksman rifle (scout rifle) with a scope.
Darkzone is great, although how long it'll last I'm not so sure. Only played solo so far, and a successful extraction is a hella tense affair.
All in all, pretty sure this is likely a very solid PVE Destiny-alike to play and pass the time while there's no real Destiny to be played. The PVP I am not so sure. It's good, no doubt - but it isn't the usual TDM / Control and isn't likely to fill that gap.
edit: lol I dropped a weapon skin super early on also
haven't seen another on a random yet! Mine is bright blue lol
