Visuals & Engine: Built in Unreal Engine 5 (4K, 60+ FPS) featuring improved visuals, richer sound, and added environmental details like wildlife.

Modern Mechanics: Adds sprint, clamber, ground pounds, vehicle hijacking, and improved enemy AI.

Rebalanced Arsenal: Weapons feel refreshed; the Needler and Needle Rifle are far more effective, while the iconic pistol remains strong.

Bonus Prequel Levels: Set one year before the main story, these new missions omit Cortana, feature Sergeant Johnson, and support chaotic four-player co-op.

Performance: Plays great on PC and ROG Ally X, but performance is poor on the original white ROG Ally.

No Microtransactions: All cosmetics, such as alternate Master Chief skins, are earned strictly through gameplay.
