Game Revolution
- "If you've got the online connection, there's fun to be had with AFO. Sure, the online server could have been better geared for game matching and keyboard support on top of the voice chat wouldn't have hurt, but the simple action and smooth gameplay

IGN
- "AFO really shines when you get eight players in the heat of battle, and when the game releases, players will know how war is truly hell and a crazy, trash-talking, teeth-grinding, fun type of hell." [8.5/10]

Gaming Age
- Review by Sean Ireland, [C+]. "The real-time chat feature practically makes the game. There's room for much more depth, but AFO is a great pick-up and play shooter, or 7-day rental." Review by Sean Ireland.
