Rockstar Games has announced that the Legends and Killers downloadable content (DLC) for the studio’s Wild West open-world action game, Red Dead Redemption, is now available to purchase and download on Xbox 360 via Xbox LIVE.

The PS3 version of the DLC will become available later today with the usual PlayStation Store update for North America, and tomorrow for European PlayStation Network users.

For 800 MS Points on Xbox 360, you’ll gain access to the following:

“The Legends and Killers Pack doubles the amount of competitive multiplayer territories with nine new map locations that are weapon-balanced specifically for multiplayer and packed with free-for-all and team-based challenges. New locations vary from the fog-filled riverside at Thieves’ Landing to the modern metropolis of Blackwater.

“Eight classic personalities from 2004’s Red Dead Revolver return as multiplayer characters, including fan favorites Red Harlow, Jack Swift, Annie Stoakes and Shadow Wolf, among others. Available in competitive multiplayer, free roam and single-player modes, the Tomahawk, a deadly new projectile weapon, introduces more ways to eliminate the competition.

“In addition to gameplay challenges, the pack also presents additional opportunities to earn Achievements and Trophies.”

Founder of Rockstar Games Sam Houser said of the new Red Dead Redemption content:

“With Legends & Killers we wanted to provide a wealth of new content for fans of Red Dead Redemption. We took care to pick out areas that were unique and exciting and then polished them to provide the best possible multiplayer experience.”
