Halo 3

1 story
Halo 3 gives its first-person shooter identity a clear focus through four-player online cooperative campaign, Theater replay mode and competitive multiplayer, creating a pace shaped by positioning, resources and execution. The story follows Master Chief, with Arbiter Thel Vadam and Sergeant Avery Johnson providing support and Prophet of Truth and Gravemind forming the main opposition.
Different encounters make room for Cortana artificial intelligence, Commander Miranda Keyes and UNSC faction; the combination creates meaningful differences between mission types. The most relevant subjects for Halo 3 are mode design, network performance and player strategy, and the relationship between Earth battle and the campaign.
