Halo 2

Halo 2 is the sequel to Halo: Combat Evolved and continues Master Chief’s war against the Covenant as the fight reaches Earth. Developed by Bungie, it splits its campaign between the Chief and the Arbiter, a Covenant Elite whose story shows the war from the other side.

It added dual-wielding, new weapons and vehicles, and online multiplayer built around matchmaking. On Xbox it’s available as Halo 2: Anniversary in Halo: The Master Chief Collection, with remastered visuals and the option to switch back to the original graphics.
