Rex Infernus hides several powerful masks behind unique Easter egg challenges, and each one can dramatically improve your survival potential during high rounds. From the Skull Mask's Stone Cold Stronghold effect to the Forest Mask's lightning attacks, these collectibles offer useful advantages for different playstyles. Before tackling the challenges, players can also buy Call of Duty Black Ops 7 Bot Lobbies at MMOEXP to practice movement, combat, and survival techniques before taking on tougher Zombies objectives.
Important: The source material describes four masks initially, but it also includes the Forest Mask, making five distinct masks covered in this guide.
Skull Mask: Create Your Own Circle of Death
The Skull Mask is obtained through the painting Easter egg in Her House. Stay there until Round 8, then melee the painting to the right of the fireplace, opposite Quick Revive. A reward will appear every few rounds, but do not collect the rewards. Your third reward will eventually be the Skull Mask.
The mask provides the Stone Cold Stronghold effect. Stand completely still to create a purple ring of fire around your character. Zombies entering the ring are instantly killed, although the protection only lasts for roughly three seconds before needing to be activated again.
The mask can later be found on a pedestal in Veytharion Sanctuary.
Key takeaway: The Skull Mask is excellent for quickly eliminating zombies that crowd around a stationary player.
Astronaut Helmet: Grapple Longer and Ignore Falls
The Astronaut Helmet requires collecting six pieces of Mister Peeks using the Void Claw. The pieces can be found at Her House, Nexus Forge, Caltheris Passage, Ruinas Insula, Aranea Insula, and Spira Insula.
After collecting all six, open the entire map and visit Caltheris's Sanctuary. Find Mister Peeks on the platform above the Mystery Box and complete his grapple-hook time trial in under 60 seconds twice.
The reward provides fall-damage immunity and doubles the amount of time you can hold the Void Claw. It does not protect you from falling into the map's abyss.
Key takeaway: This is one of the best mobility-focused masks for players who frequently use the Void Claw.
Warden's Hat: Become Immune to Web Slowdowns
The Warden's Hat is designed specifically to counter Rex Infernus's web-based enemies. From Round 16 onward, use the Void Claw to mount a Web Mother and kill more than 75 zombies while riding it.
Once you've reached the required number, travel to the Nexus Forge and use the Void Claw on the Web Mother beside Pack-a-Punch. It should jump and die, causing the Warden's Hat to appear.
The hat makes you immune to the slowing effect caused by webs, including attacks from Deathspinners and Web Mothers. These enemies can still damage you, but their ability to slow you is removed.
You can find the mask at Nyxara's Inner Sanctum after completing the Warden's Blight wonder weapon quest.
Key takeaway: The Warden's Hat is particularly valuable during rounds where web enemies become a major threat.
Forest Mask: Bring Lightning to the Horde
The Forest Mask becomes available after opening Nyxara's Inner Sanctum during the Warden's Blight wonder weapon quest.
Each round, interact with the fruit at the tree's roots to teleport to the Forest. Find the tree stump with the music box, then return and visit the Forest again during the following round. A toy box will appear between two trees.
Interact with it to complete three minigames. After finishing them, repeat the same three challenges at a higher difficulty. Completing the second set causes the Forest Mask to appear from the tree roots when you return to Nyxara's Inner Sanctum.
The mask can randomly trigger while killing zombies, calling down a lightning bolt that electrocutes zombie groups. Its effect resembles Dead Wire and can stack with an existing Ammo Mod. The Twins also perform their own dance when the effect activates.
Key takeaway: The Forest Mask provides extra crowd-control damage without replacing your existing Ammo Mod.
Helpful Tips for Unlocking the Masks
·Complete mask objectives during rounds where enemy pressure is manageable.
·Keep track of Mister Peeks locations before attempting the Astronaut Helmet challenge.
·Practice Void Claw movement before attempting the 60-second time trials.
·Save the Warden's Hat challenge for a run where you can safely farm Web Mothers.
·Don't overlook the Forest Mask's minigames; they require multiple visits.
·Choose your mask according to your strategy rather than simply using the newest unlock.
·Practice difficult Easter egg mechanics in Call of Duty Black Ops 7 Bot Lobbies before attempting them during serious high-round runs.
Final Takeaway: Rex Infernus Has a Mask for Every Playstyle
The masks hidden throughout Rex Infernus aren't merely cosmetic collectibles. The Skull Mask provides powerful stationary protection, the Astronaut Helmet improves mobility, the Warden's Hat counters web slowdowns, and the Forest Mask adds additional lightning-based crowd control. Collecting them all gives you more options when preparing for increasingly difficult rounds.
If you're ready to master Rex Infernus and want extra practice with combat and movement techniques, buy CoD Black Ops 7 Bot Lobbies at MMOEXP to level up your game before taking on the map's toughest Zombies challenges.
