Campaign

Campaign Mode is the single player gaming aspect of Halo: Combat Evolved, Halo 2, and Halo 3, where the player takes control of a single character at a time through the canonical storyline of the Halo trilogy. In Halo Wars, the player takes control of an entire UNSC army force, although some UNSC are non-controllable.

Description
In Halo: Combat Evolved and Halo 3 the player plays as John-117 or Master Chief, in Halo 2 the player plays as both Master Chief and the Arbiter Thel 'Vadam a Covenant Elite, which allows the player a more personal view on Covenant society.

In Halo Wars, the campaign has a different gaming aspect. The game is a strategy video game, and the player takes control of a whole base, troops and vehicles. It is up to him to decide where a squad will go, when a building will be constructed e.g. Again, the game follows the canonical storyline of the Halo Universe.

It can be played on four difficulty levels (There is a fifth difficulty which is the highest of all the difficulties known as iron which is only unlocked in Halo 2 and Halo 3 through the collection of the Iron skull), listed in order from most difficult to the easiest: Legendary, Heroic, Normal, and Easy. In addition, Halo: CE and Halo 2 have a co-op Campaign option permitting two players to play through campaign either in split-screen or via system link between 2 Xbox's. For Halo 3 the number of players permitted has changed to allow up to 4 players and the use of Xbox Live.

Halo 3 also has two unique, unofficial difficulties known to fans. One of them is Mythic, Legendary with the Mythic skull activated and the other being Ultra. Ultra is played with ALL skulls activated.

Trivia

 * All of the trilogy games end with Master Chief in space with some kind of transport. 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.
 * All of the trilogy games also begin with the Master Chief in space. In Halo: Combat Evolved he is on the Pillar of Autumn; in Halo 2 he is on Cairo Station; and in Halo 3, he is on the Dreadnought, but only briefly.
 * Halo: Combat Evolved starts with Master Chief leaving a cryo pod and Halo 3 ends with him entering one again.
 * There are 35 levels total in the Halo Trilogy. 35/5=7. Another Seven reference.
 * 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.
 * In Halo: Combat Evolved, Halo 3 and Halo Wars, the endings of all three games end with an explosion: Halo: CE ends with Halo Installation 04 exploding, Halo 3 ends with Halo Installation 04 (II) exploding, and Halo Wars ends with a Shield World exploding.
