I've played around with it a bit and it's pretty good although there is WAY too much bloom and blur. I realise that's to be expected of any FPS released in the past 5 years but it's still annoying.
The classes are cool and the unique abilities are nice and varied although some are almost entirely based around the idea that you play as a team, something that can usually only be achieved by playing with friends.
The maps and game modes are quite well designed, I really like the Warzone mode that cycles through random objectives until the game ends, whichever team won more objectives wins the overall game. The maps are big enough that 24 players can run around without it being a constant clusterfuck but you still see it happen sometimes because people are retarded and can't understand the concept of working as a team in any way that's not a zerg rush.
There's sometimes a bit of frame rate lag when there are multiple people + explosions on screen at once but, assuming you're playing on local servers (there's an option to choose which ones you want to connect to), it's not that big of an issue.
