Yeah I've been playing it for a while now and have gotten my guy up to lvl 30. Its a pretty well balanced game and I give it a thumbs up. However it's not without its bugs and poor programming choices... such as movement glitches, missions that underestimate the level at which the mission is able to be accomplished, and of course, buggy boss fights that you have to glitch out in order to beat. But over all I give it 2 thumbs up.
This game was totally unappealing. Lame voice acting, downright cheesy plot, and on top of that, combat just wasn't fun. If I want a Shoot shoot bang bang FPS, I'll play TF2. Which I have.
