The first downloadable boxer pack for EA’s Fight Night Round 4 will be available in late August on Xbox Live and the PlayStation Network.

The downloadable boxer pack will include Oscar De La Hoya, Vitali Klitschko and Wladimir Klitschko as well as alternate versions of George Foreman and James Toney. It will cost 800 Microsoft Points or $9.99.

The publisher will also be releasing a free downloadable game update at the end of August.

In addition to new trunks, gloves and shorts, gamers will be able to throw punches, hooks, uppercuts and haymakers using the face buttons on the Xbox 360 and PS3 controllers thanks to a free button control scheme that will be included in the update.

A new 12 round demo featuring the button controls will land on Xbox Live and the PlayStation Network by early September. The demo will feature Mike Tyson and Muhammad Ali as playable boxers.

Fight Night Round 4 is available now for the PS3 and Xbox 360.

“We are extremely excited to be able to add Oscar and the Klitschko brothers as part of our roster,” said executive producer, Dean Richards. “As three of the most globally recognized names in the sport, they are an important addition to the Fight Night Round 4 lineup.
