Coming as good news to Gears of War-heads, Microsoft has announced that the Hidden Fronts Map Pack, which has become the number 1 premium downloadable content on Xbox Live, will be released for free on September 3 (coming Monday). This map pack joins the Annex gametype and multiplayer map pack 1 as another piece of free DLC for the game.

This ex-premium pack contains four new maps, including Bullet Marsh, Garden, Process and Subway. Here’s the scoop:

Bullet Marsh
In this Kryll-infested swamp, an old generator still powers the area lights. A few stray bullets could easily knock out the generator, leaving combatants to fend for themselves against the Kryll.

Garden
This overgrown and crumbling conservatory still has a working fertilization and pesticide system. This system can pose a serious hazard to anyone who ventures into the greenhouse without first venting the air.

Process
Fight for control of this subterranean Imulsion processing plant, still active despite the cessation of the Pendulum wars.

Subway
Timgad ‘s Central Subway station used to serve as a central hub for commuters. Now the tunnels are crawling with Locust.

Gears of War was released on Xbox 360 to wide critical acclaim and great sales last year. It is being released this November on PC, which will include exclusive content and DX10 support.
