5 things Halo: Campaign Evolved adds

Halo: Campaign Evolved is a 2026 remake of Halo: Combat Evolved with new missions, weapons, and co-op.

Halo: Campaign Evolved is a full remake of Halo: Combat Evolved with 10 original missions, 3 new prequel missions, and release plans for Xbox Series X/S, PC, and PlayStation 5.

1. A full remake, not just a visual refresh

The biggest change is that Halo: Campaign Evolved is built as a complete remake in Unreal Engine 5, not a simple remaster. Halopedia notes that it reworks gameplay, art, voice acting, music, and even story content so it can work as a modern first Halo entry.

That matters for players who want the original campaign feel without the rough edges of 2001 design. The remake keeps the core mission structure, but it updates the experience in ways that affect how the game plays from moment to moment.

• Engine: Unreal Engine 5
• Developer: Halo Studios
• Publisher: Xbox Game Studios
• Release window: 2026

2. Three new prequel missions

Campaign Evolved includes all 10 original missions from Combat Evolved, plus 3 new prequel missions set before the main story. Those additions focus on Master Chief and Sergeant Johnson, which gives the remake a bit more narrative room without replacing the classic campaign.

For longtime Halo players, this is the most interesting story change. It adds new material to a familiar game while keeping the original campaign intact, so the remake can expand the lore instead of rewriting it.

• Original missions included: 10
• New missions added: 3
• Story focus: Master Chief and Sergeant Johnson
• Placement: before the events of Combat Evolved

3. More co-op options than the original

The original Halo: Combat Evolved supported two-player co-op, but Campaign Evolved expands that setup. The remake supports single-player, two-player split-screen on console, and up to four players online, which makes it easier to bring a full squad into the campaign.

This is one of the clearest quality-of-life upgrades. The larger player count also affects level spaces, since some areas have been adjusted to fit more players without breaking the mission flow.

4. New weapons, vehicle play, and sprint

Campaign Evolved keeps the original weapon set, then adds nine new weapons for the campaign. It also lets players drive the Wraith, board vehicles, and use a Warthog with a fourth rear seat, so fireteams can stay together more easily during vehicle-heavy missions.

Movement and combat are more flexible too. Sprint is included, though players can turn it off for a classic-style run, and some older weapons now have aiming behavior closer to later Halo games like Halo 5: Guardians and Halo Infinite.

• New weapons include the energy sword, battle rifle, fuel rod gun, sentinel beam, and needle rifle
• Vehicle additions: Wraith driving and vehicle boarding
• Warthog update: fourth seat on the rear bumper
• Sprint: on by default, optional to disable

5. Redone audio, collectibles, and customization

The remake also updates the soundscape. Halopedia says the game includes a remastered score that recreates the original soundtrack, plus redone sound effects and re-recorded voice acting from the principal cast. In some cases, the dialogue is expanded, and 343 Guilty Spark gets new lines in The Library for added context.

There are also new skulls, text terminals, and armor customization for Master Chief’s Mark V MJOLNIR armor. Those additions give completionists and repeat players more reasons to revisit the campaign after the first run.

• Audio: remastered score plus new sound effects
• Voice work: re-recorded by the principal cast
• Collectibles: new skulls and text terminals
• Customization: skin options for Master Chief’s armor

How to decide

If you want the most faithful version of the original campaign with modern presentation, Campaign Evolved is for you. If you care most about new story material, the three prequel missions are the main draw. If you play Halo with friends, the four-player online co-op and console split-screen support may matter more than any visual upgrade.

For players who are curious about Halo on PlayStation 5, this remake is also notable for being the first mainline Halo release planned for that platform.
