Next, look for a ledge at the back of that room and grapple your way up to that ledge.

Turn your flashlight on once you’re up on the ledge and turn around to face the portal. From here, turn to your right, look up, and you’ll see a ledge you must rappel up.

One of the classic skulls you will find next is called the Grunt Birthday Party skull.You will find this skull in the Repository mission.Entering the area, you will notice a blue transparent bridge you will need to cross. Next, you will want to interact with the pedestal in the middle of this platform which will extend the light bridge.
While still on the middle platform, you will notice on the left and right of you are these doors.Go back to where you entered, and you will go to the door on the right.Either jump at it with your grappleshot or to play it safe, run back the way you came and follow the small ledges on the right to jump from the entrance of the room inthis Xbox original franchise.

Go through the secret door and at the end of the hallway you will find a power cell.Grab the power cell and bring it to the door on the opposite end of the room. To make things easier, throw it back to the beginning of the room, so it doesn’t fall into the void. You will then follow suit and pick it up once you’re at the entrance again.
After you pick the power cell back up,take it to the center and throw it to the door on your left before grappling over to the door.Once you grab the power cell again, enter that left-hand side door, go down the hallway, then to your right you will come to a small pedestal you will want to plant the power cell. You will then continue on with the mission for a couple more minutes.

From here, you will enter the next door in the mission, up a ramp then into a room. Two pillars will be in front of you,and you’ll want to grapple up them.You will come to a glass window which will be opened because of you moving the power cell.
