Note: The Call of the Dead map pack update is required. You also must activate three meteorites. The first meteorite can be found right in the starting area by the canister. For the second one, you must reach 750 points. Open the path to the right (while facing the lake) of the starting area and head upstairs, then pass the blockade and enter the room with the tables. On the far side is a meteorite lying on the seat. You'll need 750 points to open the path to the lighthouse. Underneath the large staircase, leading up to the lighthouse, is a room. Facing the staircase, turn right and make your way to the room below. The meteorite is here. After finding it, "I'm Not Ready to Die" by Avenged Sevenfold will play.
