Live beta starts in an hour.
It's not bad. A little clunky in a few areas but those are addressed in the full game. The hub feels weird, maybe because it's not the 'full' thing yet but it's busy. I was walking past an NPC and he bumped into another NPC and there was an animation for it. Whoa, bro.
The weapons feel good. My only complaint is the flying feels awkward on a controller and could take some practice.
Enemies are pretty legit. I nearly died because they combo'd me. You aren't a walking monstrosity, your first suit gets beat up pretty quick but can still hold its own in a fire fight.
