Trivia

 * All of the games end with Master Chief in space. In Halo: Combat Evolved, he is in a Longsword. In Halo 2, he is in the Forerunner Dreadnought. In Halo 3, Master Chief is stranded in the remains of the UNSC Frigate, Forward Unto Dawn, which is drifting in an unknown part of space.
 * Halo: Combat Evolved starts with Master Chief leaving a cryo pod and Halo 3 ends with him entering one.
 * In every game the Master Chief falls unconscious. In Halo: Combat Evolved he is unconscious after the escape pod crashes at the beginning of the level Halo. In Halo 2, he is knocked out when the Pelican crashes. In Halo 3, he is unconscious at the beginning of Sierra 117 after landing on the ground after leaving the Forerunner Dreadnought.
