Halo: Campaign Evolved is a faithful yet modernized remake of Halo: Combat Evolved's campaign. Experience the original story rebuilt with high-definition visuals, updated cinematics, refined controls, plus a brand-new three-mission adventure featuring the Master Chief and Sgt. Johnson. A broader arsenal of weapons, vehicles, enemies, and gameplay-modifying 'Skulls' – optional modifiers that change combat in fun and challenging ways – add fresh tactics and endless replayability. Play it your way: solo or up to 4-player online co-op with full crossplay and cross-progression support. Whether you're discovering Halo for the first time or returning to the ring after 25 years, Halo: Campaign Evolved delivers an adventure that feels both timeless and brand new.
