First impressions, having gone through the tutorial and poked around the menus.
One: I hope there's never PvP because unless you pay to "go pro" you can't upgrade your weapons as much, and I'm talking upgrades, not side grades - flat increases to damage, RoF, clip size etc.
Two: It might just be me, but the skills don't seem to work. I'll play a bit more and see what's what, but the skill in the tutorial wouldn't activate for me, which was rather irritating.
Three: Urghhhh mouse sensitivity in menus. It can't be changed, and it's really slow, so it's annoying to navigate things when you have to drag your mouse all the way across the mouse pad again and again.
Four: Controller vibration won't turn off, which is irritating, because it means I have to rest my controller on top of my hat so it isn't vibrating against my PC tower next to the desk. Oh well.
Okay, some more things after having played the first mission.
Grenades are bullshit. There's no indication they're there and they're likely to instakill you, which means spending a revive or going back to the last checkpoint, which can often be quite far back. Revives are purchased using the realmoneys currency, platinum.
It's horribly cover-based, with no actual cover mechanics. You will be hiding behind walls, angling the camera to see your enemies and shoot at them while they can't shoot at you.
The game has a class-system in the form of different exo suits. Buying exo suits costs Platinum.
I honestly can't enjoy this game. It just has too many points like this that all add up to it being bleh. I know, beta is beta, but if it's this bad now, what are the chances it'll be even semi-decent when it's released?
