I have never really been into shooters or online play at all, but I absolutely adored this game. I was so addicted to it, it probably has the most playtime out of all the PS3 games I own.
It's fine if you're a noob since there are ranked matches which allow you to suck and get away with it.
The online community for Warhawk is still huge as far as I can tell, theres even a league for it on this site if I remember correctly.
As in go buy us some coffee.
