According to Kotaku (and some press releases) Epic will offer two FREE 'Gears of War' maps for download on Xbox Live for the 360.

The descriptions of the maps are as follows:

"Raven Down: A Raven Helicopter has gone down in the middle of a large scale battle with the omnipresent Locust Horde. Gears have taken out the Seeder and gamers join Delta Forces moving into the crash site from all angles to search for survivors."

and

"Old Bones: In an attempt to eradicate any traces of human history and culture, the Locust Horde has emerged under Sera's Capitaline Museums and has begun to destroy them brick by brick. Each gamer's mission is to help the Delta Force recapture the museums before all remnants of humankind's existence are obliterated."

These freebies should be available for download on January 10th!
