Halo: Campaign Evolved introduces significant enhancements to the original Halo: Combat Evolved, including Operation: METEORITE, which features three new bonus missions set a year before the main campaign, focusing on the Master Chief and Sergeant Johnson. The game allows up to four players to experience the campaign together online with cross-platform play, scaling weapon spawns and adjusting levels for larger squads. Familiar collectible Skulls have been relocated, and new ones with unique gameplay modifiers have been added. Collecting three Skulls unlocks the Campaign Remix mode, which introduces new gameplay twists and visual effects. Halo: Campaign Evolved is set to launch globally on July 28, 2026, with early access for Premium Edition owners, and will be available on Xbox Series X|S, PC, and cloud, supporting cross-play and cross-progression.
