Act 1: Ashes - 5. Saviors

Grab the ammo on the ledge, and then come back and go down the steps. Be ready to catch two Wretches on the bottom. Go past the dead Seeder to the church room for a fight. Stay behind a pillar and blindfire. Follow the beaten path to the dead Alpha member.

COG #9 is to the right of the steps and in a little crevice.

Keep onwards and take out two Drones who attack you when you exit the room with the huge statue; the couches provide some cover. Bring out the Hammer and do your quick work on the Seeder, then take cover, pop up after some time, and then finish it off. Grab the ammo crate and go back to the last room. Look to the door and get a Frag in hand. Go to the left side of the door and get ready to lob a Frag inside. Then bring out the Lancer and finish them off; Grenadiers will rush if they aren't killed in the blast.

Keep onwards, picking up ammo along the way, until you reach the concrete slab; ignore the Boltok, unless you really want it, it really doesn't matter. Don't forget that some objects can be broken with the chainsaw. When you see more enemies in a room, take cover and make sure you kill the rushing Grenadier. Don't go into the big hallway. Instead, peek through the doorway to another doorway on the side and Roadie Run to it. Go up the steps and get ready for some Wretches and a Drone. Keep going and then sneak up on the gunner; please cut him in half, for me. Then man the gun and get ready for Wretches to pour from where you came from; divide your fire between top and bottom.

Keep going, don't turn right at the end of the hall, and go down the stairs. You can either shoot the guys in the room down here from the stairs, or you can go down and flank them from the left or behind. Then fill up on ammo and then follow your team to the round room. Go up the big stairs and sneak up on the gunner; then man the gun. Hope your team handles the Nemacyst and then just pick off each Drone from above. They spawn from under the tree and behind the big rock-like thing. Just be patient and you can kill them all. Watch the scene.
