Wasn't bad, the idea and design is solid, but like most other games of this genre is suffers from poorly balanced PvP. There is definitely a meta you have to follow in order to win against players who have much more gear than you do. In this game you use resources you gather from playing to "upgrade" your weapons and yourself. New players always get trounced by experienced players simply because they have access to much better weapons and armor/perks. Due to having regenerating shields/health, firefights last a very long time, and you can often just run and slide your way away from them, or likewise you can infinitely run and slide around your opponents so they can never hit you.
The core gameplay loop is fun, but winning PvP fights boils down to "do you have the upgraded gear and perks", if not you are going to lose.
