Halo: Campaign Evolved remakes the story component of which 2001 game?

Halo: Campaign Evolved remakes the story component of Halo: Combat Evolved, the 2001 game that introduced the series’ central conflict, world, and hero, Master Chief Petty Officer John-117.

The remake focuses on the original campaign rather than reproducing the first game’s competitive multiplayer. Its story follows the human warship Pillar of Autumn as it arrives at the mysterious ringworld known as Halo. After a Covenant attack, Master Chief and Cortana uncover the installation’s dangerous purpose and become entangled in a conflict involving the Flood.

Players sometimes confuse the title with Halo: Combat Evolved Anniversary, which was a 2011 remaster of the original game. Campaign Evolved is a new remake built in Unreal Engine 5, with rebuilt visuals, updated cinematics, modernized controls, new missions, and other additions while retaining the original campaign’s narrative foundation.
