The UI has got hurt somewhat review wise, understandably. However, its been received very positively - I think what helps is that Arc Raiders is the chill PvEvP game more weighted to PvE, whereas this is more weighted to PvP. Having said that, theres lots of puzzles to explore and with Arc Raiders content delivery pattern not helping certain players (including myself), I can see why this has appeal.
We're into an era of playing more than one game is the way forward because one game these days can't satisfy consumers enough as they don't evolve quick enough (whether I agree with that or not, its just gaming right now).
The gunplay looks everything I expected it to be. I'm trying it over the next week. Hopefully not going to get stuck in UI admin, which is a real killer.
