Gears of War 2 is one of the Xbox 360’s biggest moneymakers so the onslaught of map packs and the like are no surprise. In fact, hype surrounding the game was so big that it recently managed to surpass a 5 million copies sold milestone.

In leui of this announcement, Epic has announced that they will be releasing a retail only content pack entitled All Fronts which includes all Gears 2 map packs released thus far. However, All Fronts will also include the all new Dark Corners map pack complete with 7 multiplayer maps and the deleted campaign chapter Road to Ruin.

All Front is set to hit retailers on July 28th. If you have a fear of leaving your house or just purchased all of the map packs already, you can buy just Dark Corners off of Xbox Live for 1600 Microsoft Points.

Allfathers Garden: Honor the sacred grounds of the Coalition founders in this explosive map, where powerful weapons catalyze fast and furious action at this COG landmark.

Memorial: Set near the Eternal Flame, which pays tribute to the fallen soldiers on the battlefield, a hard-fought battle ensues at the Tomb of Unknowns. Putting their flank formation and evasive skills to the test, players will fight to control the Boomshot.

Sanctuary: Once a peaceful ground for reflection and remembrance, all that remains of the Sanctuary is the chill of death. Feast your eyes on the arsenal of weapons available as you make your way through the tight paths and blind corners of the Locust-damaged temple corridors.

War Machine: In the abandoned train station that once served as a hub for travel, players will need to master the Longshot, Mulcher and Boomshot weapons to advance the fight while evading fire from the platforms above.

Highway: Take the fight deep into the Locust Hollow in the complex passages of this underground highway system brimming with enemy vermin. Stick together, separate the enemy and have an exit strategy ready or it’ll be a one-way trip.

Way Station: Sitting in limbo between death and “processing” are Locust way stations filled with fallen COG soldiers. Tread lightly and practice patience as it’s better to sacrifice firepower for stealth while navigating this minefield of hidden grenades.

Nowhere: Set in the middle of what was once a destination for weary desert travellers, the land is now barren and devoid of life. Pick off your enemies with the Longshot sniper rifle and make your way to the stairwell with a well-fortified team during this intense firefight.
