ABOUT SKULLS

If you’re new to Halo, Skulls are mysterious collectibles hidden throughout campaign missions that enable gameplay-modifying features once retrieved. All you have to do is find one and pick it up—if you can reach it, that is.  

Once collected, each retrieved Skull unlocks a new pre-launch option to alter your experience in future missions with greater difficulty, additional perks, or arcade-style upgrades for added fun.  

In Halo: Campaign Evolved, there are 39 collectible Skulls to be discovered across 13 missions, with three Skulls hidden in each of the ten original campaign missions, and nine more to find throughout new missions set before the events of Halo: Combat Evolved.  

Find any three* Skulls to unlock Campaign Remix and instantly earn three additional Skulls for even more altered antics. You can check out the complete list of skulls further in this blog.

CAMPAIGN REMIX, EXPLAINED

Collect any two Skulls in Halo: Campaign Evolved to unlock Campaign Remix, an all-new play mode that allows you to revisit and replay completed missions with randomized enemies, remixed weapon pickups, new visibility effects, and a grab-bag assortment of Skulltacular delights.  

Upon unlocking Remix, the following three Skulls automatically become available for use in both mission playthroughs and Remixed campaigns.  

• Adaptation: Randomizes the enemy factions present in the mission.  

• Reload: Randomizes pre-placed weapons available in the mission.  

• Armistice: Enemy factions never fight one another.  

When deploying a Remixed mission, you’ll also get to roll for a chance to experience one of two new visibility modifiers:  

• Spore Visibility: Level visuals are blanketed in heavy, Floodified fog.  

• Nightvision: Nightvision is always on.  

Any time you play a Remixed mission, the Adaptation, Reload, and Armistice Skulls are enabled by default. You may then roll for a random visibility effect and an assortment of other gameplay-altering Skulls, with options to manually curate your experience.  

ADAPTATION AT WORK

The new Adaptation Remix Skull randomly replaces the enemy squads you’ll encounter during missions with new allotments of foes composed of different unit types or from completely different factions.  

Because Adaptation is enabled by default, you’ll find missions populated with a surprising hodge-podge of enemies and allies in near infinite-variations. A surge of Elites or a troupe of Jackal snipers? A pair of Hunters or a gaggle of Spec-ops Grunts? Maybe you’ll find Flood combat forms where you were expecting Sentinels. You might even encounter brand new enemies from the Operation: Meteorite bonus missions. That’s Adaptation at work!  

When combined with the new Armistice Skull, these random adversaries put aside their differences and form a cohesive front against all do-gooders—meaning this inter-species army has its sights set firmly on you and your allies.  

RELOADED WEAPONS

Another essential element in the Remix recipe is Reload, a Skull that randomizes all the weapon placements in your chosen mission for a Fiesta-style outing each time you play.  

Don’t be surprised to find fallen UNSC Marines beside recently relinquished fuel rod cannons, or browse a Covenant weapon rack filled with sniper rifles. All the new armaments included in the Operation: Meteorite bonus missions – such as the Battle Rifle, Brute Spiker, Needle Rifle, and more – are now also fair game for your classic campaign playthroughs.  

VISIBILITY MODIFIERS

After selecting a completed Campaign or Operation: METEORITE mission to Remix, you’ll next be prompted to roll for a randomly assigned visibility effect, with options to adjust this selection to your taste.  

When you roll for a random visibility effect, there’s a chance you could see no difference, but it’s just as likely you’ll have to contend with one of two new visibility modifiers in a uniquely dangerous scenario.  

Might want to close your mouth for this one. Spore Visibility smatters your visor with phlegmy Flood-flecks as you creep through the haze of Flood spores. 

Get tactical, marines! The Nightvision modifier deploys an espionage-ready filter over your op.

RECIPE FOR CHAOS

Once you’ve chosen a visibility setting, you can then pick and choose additional Skulls to modify gameplay however you like, or roll for a random assortment of discovered Skulls until you find a perfectly curated menu of madness.  

Seek out Skulls. Collect the carnage. Remix and repeat.  

All this chaos is even better together – jump in with up to four friends for unpredictable shenanigans and legendary challenges.
