I played it a bit. Here's my rundown:
Bad
The UI is very confusing and un-intuitive.
The Shooter part of the game felt on the right track, but I had some issues with it.
Aiming at something felt very....icky...like grease, too slippery yet also sticky.
Tried adjusting the mouse sensitivity but it didn't seem to work, no separate slider for scoped mode.
Enemies are not clearly marked, wasn't sure if I was aiming at a friendly, or an enemy, and couldn't decide if I cared about shooting either.
The game very clearly advises use of cover to avoid fire, yet presents no strategy or time to do so. I'd hide behind something, just to be shot by another guy that poped up out of nowhere.
I could never find an indicator for health/shield bars, that might just be my fault tho.
Good
The gear/loot system seems solid.
The Skill tree/grid seems like it could work for what it's doing.
The story missions were fracking entertaining. (I hope this doesn't become a new trend -.-)
Vehicles right out of the gate woo!
