Battlefield Play4Free pits the forces of the United States and Russia against each other in a 32-player online combat game for the PC that, like its "free" predecessor Battlefield Heroes, won't cost you a pretty penny to download or start playing.
Sadly, there's no word yet on what happens once you start playing for free, like how much it'll cost you to get the decent weapons or equipment.
Battlefield Play4Free combines elements of some of the more recent games in the series, like maps from Battlefield 2 and classes and weapons from Battlefield: Bad Company 2. The game launches in Q2 2011. You can sign up for its closed beta here.
