Yes if you enjoy pumping tons of bullets into enemies and just unloading on one enemy for minutes on end, this game is for you.
It's kind of like a baby between Resident Evil: Operation Raccoon City and Borderlands(minus the loot, the free roam, and the fun).
And to top things off from this grand ole studio known as EA, their trophies are glitched. I played the entire game on Hard, beat everything, and it never unlocked the trophy or the hardest difficulty. By the way, I was on my own for the majority of that time while playing online, if I was lucky about 40% of the time I had 1 co-op partner.
If you haven't played Borderlands 2 yet, go play that... then go play Defiance... then maybe you can consider this game.
It does well in the mechanics dept - decent cover and shooting mechanics.
Then the game takes you on a 6-hours trip of cover, shoot, push triangle, rinse, repeat.
On top of that you get an uninspired story with generic characters. It is a far cry from Insomniac's Resistance series.
In toto, even a rental felt like a waste of time. Go play Uncharted 2 and 3 for 3-rd person shooter with a co-op experience.
