Picked this up recently hoping they had fixed gameplay issues.
Absolutely terrible FPS. User interface has got to be the worst I've seen. Sluggish controls for vehicles, low quality FPS movements. No easy way to track progress on leveling up or guns. General dynamics of the interface is terrible. Classic based system is hard to follow and over complicated. Maps are okay, I guess.
Also, good luck finding a game. Only a few populated serves in Oceania, all are one game mode.
