Difficulty: Moderately Challenging
Step1
Fight through to the end of Chapter 1, Tick Tick Boom.
Step2
Look for a room with two staircases. At the bottom of one of them is a couch. Head down and destroy the couch. You can use the chainsaw or regular melee attacks for this, but the chainsaw is by far the faster method. Inside the ruined couch, you’ll find COG Tag #13.
Step3
Continue into Chapter 2, Grist. Go through the room where the catwalk collapses and the Wretches appear. Yes, there is a red gear on the wall here, but COG Tag #14 is NOT in this room. Head outside and go down the stairs, then turn around. COG Tag #14 is under the staircase.
Step4
Continue through Chapter 2. Just after the fight involving a pushable car and a Troika (where you tell Baird it's not over and he should reload), you’ll come to the Stranded Settlement. Walk straight ahead toward a newspaper stand BEFORE you go into the settlement. COG Tag #15 will be in the wreckage of the newspaper stand. If you miss it and walk into the Settlement, reload the chapter.
Step5
Move through the Settlement and begin Chapter 3, Lethal Dusk.
Step6
Fight your way to Checkpoint 1. A little ways after it, you’ll find yourself outside and facing Grubs coming out of an emergence hole. Fight them off, then look to the left of the hole. See a shack with a propane tank in it? Shoot the tank and look inside the shack. You’ll find COG Tag #16.
Step7
Move on and split up from Dom in order to use the spotlight to get him across the street. Wait until AFTER he has activated the lights, then move the spotlight to the left and look for a ruined car near where Dom started his run across the street. Head back down there and look around the car. You should find COG Tag #17.
