Act I: Wrath/China Shop GoW(PC) Guide

After some fighting in the corridor, you'll meet yet another Seeder. Some Hammer treatment is highly recommended here. Get back to the room you came in from - it'll get attacked by Locusts. Kill two Drones and follow your men. You shouldn't see much of a resistance. Turn right near the Troika post. Take over the gun and finish off remaining Locusts. Run after your teammates and eventually you'll reach a balcony. Destroy those spores laying about, shooting at enemies below in your spare time.

Now get ready to fight Berserker, which shouldn't be much of a challenge, provided you dodge fast enough and don't let him touch you. What you need to do is to lure him outside and destroy it with your Hammer. First things first, however. Start with backtracking towards burning debris and take 10.Tag (beside the corpse). Not far from here is the room Berserker lurks in. When it comes out, just step aside to the left, go forward and into another corridor. Stand near the door and wait for the Berserker to see you. When it charges blindly towards you dodge and, when it steps aside, go through the door. In the next room repeat the experience. Before Berserker destroys the last door, take 11.Tag from the alcove near the gate. Go outside and turn left. Behind one of the lanterns you can find 12.Tag . Finish that pesky Berserker off, using the Hammer.
