I've put in about 4 hours thus far.
Early impressions:
Good
It controls similar to BF4 but with an ability prompt on L1, camo, jetpack etc depending on class.
The scale is impressive
Visuals are nice overall considering with great effects
Framerate is smooth in small skirmishes
The sound fx
Bad
The framerate was a mess with about 50+ players fighting in a battle, it felt around 10fps at times
The hit detection is just erratic
I've been killed by friendlies more than enemies.
Some of the textures looked washed out, not sure if its 1080p, but it looks fairly blurry at times. Zooming in with the turret placement, enemies and structures just seems to wash out, I couldn't distinguish well.
Overall I couldn't help but be impressed by the scale and ambition of this game, but it just seems like a lesser version of BF that attempts to be more. None of the core elements work as well, movement, hit detection, or navigation as the BF series, but then again this is a beta.
