Experience every iconic mission in brand-new ways with Skulls, Remix, and Co-Op. When combined in this remake of Halo: Combat Evolved, these features help add nearly unlimited ways to play through the story that started it all.
— Skulls —
Featuring 42 collectible Skulls - the most gameplay-modifying Skulls ever, Halo: Campaign Evolved allows you to approach each playthrough differently.
Once collected throughout the world, Skulls unlock optional modifiers to add challenges and variety to your experience. Activate them to supercharge your Spartan with more power, face more brutally formidable foes, shift to a 3rd Person perspective, or even make confetti explode out of your fallen enemies.
— Campaign Remix —
Take advantage of Campaign Remix to add randomized weapons, altered enemy behavior, and randomized enemy encounters along with unique visual modifiers and a random assortment of up to six available Skulls from your collection.
