It's part of a summer promotion that extends through the next month or so. Aside from the new map, EA is also giving away two free Party Packs to players who log in between now and July 7 at 11:59pm PT. Each pack includes 77 Battlefunds, 25 Festive Flares, a permanent Party Hat exclusive to this promotion and a seven day rental to dress your hero in a Birthday Suit. We, uh, hope that isn't what we think it is. To snag your free Party Packs, simply log in to the Battlefield Heroes website, go through the My Stuff tab and select Rewards.
Finally, there are two new Extraordinary Hero item sets you can pick up, which not only give you a futuristic look, but also super powers such as a super jump and a speed boost. See both Metallo and Captain Royal in action above, whose super powers could be yours for a nominal fee. If only we could buy super powers in real life like that!
