Microsoft will be offering an advance deal which will bundle the first four DLC packages for Gears of War 3 for 2400 Microsoft Points (£20 apprx) in a package available on the game's launch date.
The first of the DLC packs will be launched around November, Microsoft says, with all four of the releases covered by the deal coming within a year.
The deal results in a roughly 33 per cent discount over the cost of separate purchases and buyers will also receive an in-game weapons pack.
It's not yet known whether Microsoft will be repeating the deal with other titles, but the platform holder has been contacted for comment.
Gears of War 3 launches on Xbox 360 on September 20, 2011.
