Battlefield Heroes isn't going to hit the planned Q1 '09 release. If you're one of the unfortunate many who haven't been invited into the party, EA has a quick game that may hold you over.
The official Battlefield Heroes website has released a Flash version of the game to help pass the time before the open beta begins. In the Battlefield Heroes Flash Game players have 60 seconds to shoot as many "Nationals" as they can, who each pop into frame Wack-A-Mole style and await a bullet sandwich. It isn't as sexy as playing the real game, but ... yeah, we got nothing.
