Level 9: Keyes

Overshield 1: After falling into the large pit and exiting the cruiser, proceed towards the gravity lift. Before crossing the coolant to reach the gravity lift, you will find an Overshield next to the coolant.

Overshield 2: Once you re-enter the ship, navigate through the hallways until you reach a large room where Cortana remarks, "Look, in the corners. The Flood are gathering bodies here." Proceed to the lowest floor where the Flood are present. Next to one of the locked doors, an Overshield is located. Be aware that a door will open to your right, releasing numerous Combat Forms.

Active Camouflage 1: From the start of the level, enter the door directly across from your starting position. In this hallway, you will observe a Grunt being pursued by a Combat Form. Open the door from which they emerged to find an Active Camouflage, which will be beneficial for the subsequent section of the map.
