Requiem Campaign

Lore & Background

Requiem is a Forerunner shield world that serves as the primary setting for Halo 4's campaign. As Master Chief and Cortana explore Requiem, they fight hostile forces from a new Covenant faction and mechanical warriors called 'Promethean Knights'. Cortana malfunctions and reveals she is experiencing 'rampancy', a declining mental state faced by smart AIs past their usual seven year life-span. Chief promises to get Cortana to Earth, believing that Cortana's creator, Doctor Catherine Halsey, can fix Cortana's condition. Chief and Cortana pick up garbled transmissions from a human ship, UNSC Infinity, who have picked up the Forward Unto Dawn's distress call. Cortana attempts to warn Infinity away from Requiem's gravity well and directs them away from danger.

Reader's Guide

The campaign mode can be played alone or cooperatively with one other player on the same console via split screen, and up to three other players through Xbox Live. Unlike in Halo 3 cooperative campaign where each player takes the role of a different character, in Halo 4 all players assume the role of Master Chief. Players can enable 'skulls' in the campaign menu which act as gameplay modifiers such as increasing enemy health, changing NPC behavior or removing elements of the player's HUD. The campaign also features terminals which provide the player with additional backstory via videos viewed in the Halo Waypoint application on the Xbox 360.
