Characters and setting.

Halo's storyline is linear, there is a single ending in contrast to other first person shooters such as Deux Ex that could have several different endings. The storyline is presented to the player through an instruction manual, scripted events, and conversations during the game, and a number of cutscenes rendered using the game's graphic engine. This method of storyline delivery is common among modern video games. The Xbox version of Halo: Combat Evolved allows one player to play through the campaign alone, as well as allowing two players to play through the campaign in split-screen together. The PC version of Halo: Combat Evolved allows only one player to play through the campaign.

Plot Synopsis

Spoiler Warning: Plot and/or ending details follow.

Halo: Combat Evolved begins with the UNSC Pillar of Autumn emerging out of slip space after the Fall of Reach, only to find a huge ring world, commonly called Halo, called Installation 04 floating in space. Master Chief Petty Officer John-117(although his name is never mentioned throughout this game), an SPARTAN-II, is aboard the UNSC Pillar of Autumn when the ship comes under attack by The Covenant, a religious alliance of aliens and the archenemy of humanity.

With the ship about to be overrun, Captain Jacob Keyes, the commander of the Autumn, orders John-117 to protect the ships Artificial Intelligence ( known as AI) called Cortana. She carries highly sensitive information about the United Nations Space Command, including the location of Earth, which would prove disastrous is captured by the Covenant. John-117 evacuates the doomed ship for the surface of the Halo ring to protect Cortana. With the UNSC Marines by his side, Cortana providing direction, and his assault rifle ready and loaded, John-117 sets out to uncover the mysteries of Halo and the fight the Covenant.

After meeting up with surviving UNSC forces under Staff Sergeant Avery Johnson, John-117 participates in a mission to rescue Captain Keyes from the Covenant cruiser Truth and Reconciliation. After rescuing Keyes, Cortana learns that the ring appears to be a weapon that holds great religious significance to the Covenant. Realizing that the Covenant cannot be allowed to control Halo, Keyes dispatches John-117 to secure Halo's control room while Keyes leaves with Johnson to secure a Covenant weapons cache.

With UNSC Marines as support, John-117 leads an assault on the Silent Cartographer, a map room which holds information on every location on the ring, including the control room. Heading to the ring's control room, Cortana is inserted in the ring's computer system and learns that Halo was made by the Forerunners, an ancient alien race that the Covenant worship as Gods. However, Cortana soon learns that there is something else on Halo, something that terrifies the Covenant. Frightened, she says that John must stop Keyes from accessing the 'weapons cache' before it is too late. John-117 leaves for the last spot where Captain Keyes and Sergeant Johnson's squad were seen, an underground facility in a swamp. He finds evidence of battle all over the facility and soon finds the recording of one Marine, Wallace.A.Jenkins, which details Keyes' squad encountering a new threat: The Flood.
