I agree with Gunny... I'm enjoying the game (although I haven't been on as much as I'd like due to prior commitments, and last night, exhaustion.) I'm level 23 or 24 currently. The unlocks and burn cards keep it interesting, as does the experience system and prestige cards.
I do agree with the end of this review, however. This game needs community features badly if it wants to sustain viability over the course of time.

PC Gamer Review

Private servers, along with the ability to tour maps and practice them are essential. If they don't come sooner, rather than later, the competitive community will move on.
