As a Labor Day gift just for you (for being such a great person) the Gears of War map pack Hidden Fronts will be made free for download on September 3rd. Microsoft has got to be sad to let it go, too - it's been downloaded over 500,000 times and is the best-selling content on the entire Live Marketplace. Here's a summary of the maps you'll get:

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.
