The video game's world is obsessed with blood-sucking demons and vicious werewolves, but we didn't expect them to turn up on the battlfields of EA's Play 4 Free third-person shooter, Battlefield Heroes.

In a special month long event, the many millions of Heroes who have perished on the battlefield can be brought back to life. Anyone can fight alongside these preternatural beings but to become one players must purchase the all-new outfits as a special bundle on the website or as separate items in the in-game store.

Once-dead Nationals can be transformed into blood-sucking vampires and Royals into teeth bearing werewolves. Three existing maps have been converted to an eerie night setting to set the stage for a battle between these immortal enemies.

Battlefield Heroes features signature Battlefield sandbox gameplay, a built-in matchmaking system, character customistaion and the option to upgrade items for Valor points.
