Johnson Disappearing on the Cairo is a glitch in Halo 2's Campaign level Cairo Station. The glitch causes Sergeant Johnson to suddenly disappear during gameplay.

Obtain an Energy Sword from an Ultra Elite. When you meet up with Miranda Keyes, kill all of the Covenant forces in the area. Use the Energy Sword to slash Johnson in the direction of the door -- on a side note, note that Johnson is breathing in space. After killing the Rangers, continue to slash Johnson toward the fire control center. After you get Johnson in the elevator, he will disappear as soon as Fleet Admiral Harper starts talking.
