Loot Ninja got the retail version of Warhawk today from Sony for PS3 with the Jabra bluetooth headset. Their first impressions: this will be a must have for the PS3 if you like online shooters (the game is online only).
The game can have up to 4 people on each PS3 both offline and online. No other "next-gen" online games have supported 4 players on one console. Warhawk allows you to get 3 other friends at your house to play online against the world. Games support up to 32 players simultaneously. Loot Ninja has been in games with 32 players with absolutely no lag (for the record, they haven't seen any lag in Warhawk with the beta or final release). Warhawk has all your standard online modes, including Team Deathmatch, Zone Mode (territory holding), and Capture the Flag.
