Gears of War 3 - Ashes to Ashes

Welcome to Char. For the most part, you're in a pretty quiet area. Just keep going until weird stuff starts happening. The first time you get shot at, just duck and cover until it stops but otherwise just follow the path. When you get shot at by a sniper and he misses poorly, take a couple steps back. After that, you'll enter an area with a kid's park. Off to the left side of the door to exit the area is a single room building and in the middle of it are COG tags.

Go through the big door and in the next room, on the left will be a room with ammo and just before you leave the building, if you turn around there will be a shut door with ammo, frags, and a longshot. As you exit, watching falling objects and step back until Jace finishes yelling. Then continue on and you hear the baby crying, investigate slowly. Continue to follow after the Ash Man and watch out for a falling cart and some polyps.

When you finally start getting shot at for real, you can close in a little but not too far because you'll have stalks coming up in the middle of the area. Clear that out and then you'll get to meet the Ash Man.
