Collectible (1/1): This collectible is at the very end of the chapter. After crossing the bridge with the Troika gunner, Drones, and Theron on it, do not activate either of the terminals beyond the archway. One of them serves as a collectible, and if you activate the wrong terminal you'll have to restart the chapter to get it. After passing through the archway, activate the Locust Terminal to your RIGHT. You'll know it's the collectible because the icon at the bottom of the screen will be a magnifying glass rather than a switch.
