Red Dead back in the DLC saddle

Rockstar Games has announced that it intends to release at least four more pieces of paid downloadable content for its chart-topping Red Dead Redemption before the year is out.

All four DLC packs will be released on both Xbox 360 and PlayStation 3, released regularly between the beginning of next month and the Undead Nightmare add-on at an unspecified point in Autumn.

"We want to continue to provide Red Dead Redemption's fans with a steady supply of innovative new content," said Sam Houser, founder of Rockstar Games. "Our goal is to continue to pack as much entertaining gameplay and as many surprises as we can into the massive world of Red Dead Redemption over the coming months."

Three of the four packs are priced at $9.99, with the fourth's pricing unconfirmed. It is perhaps likely that the Undead Nightmare DLC arrive release around Halloween, and could be an attempt to rival the anticipated follow-up to Call of Duty's successful Nazi Zombies mode in the upcoming CoD: Black Ops.

Red Read Redemption has proved perhaps the year's biggest hit so far, so the new DLC is likely to be enormously profitable for Rockstar.

Last week, NPD figures revealed that the game hold sold 1.5 million units during May in the US alone.

Additionally, Rockstar released statistics stating that players had 17 million hours of worldwide playtime in the first two weeks of the game's global availability. 132 million in-game murders were "committed" during that time.
