Cube Glitch

The first method is to use the Pelican/Phantom easter egg in New Alexandria. Without boundaries, the player/players can travel out of the map and through the Covenant Cruiser Models.

The second is to use Theater mode. On the Pillar of Autumn, the player can lift the camera up and through the Covenant Cruiser.

The sphere can be found by going out of the map on Long Night of Solace in Theater mode. It is beyond the Launch Facility
