The iconic Call of Duty Zombies map Ascension features several complex easter eggs and hidden secrets for players to discover. From the multi-step main quest to hidden musical tracks, this classic Soviet cosmodrome setting is packed with interactive lore and rewards.

The Casimir Mechanism Main Quest

The primary easter egg on Ascension is known as the Casimir Mechanism quest, which tasks players with freeing Soviet scientist Anton Gersh. Completing this multi-step storyline requires a coordinated squad to handle specific equipment like Gersh Devices and Matryoshka Dolls.

Players must activate power generators, hit synchronized switches during Space Monkey rounds, and spell out words using the Lunar Landers. Successful completion awards all players with a temporary Death Machine and full perk rewards.

Hidden Musical Easter Eggs

Ascension contains musical secrets that players can trigger by finding specific interactive objects hidden around the map. Interacting with three distinct teddy bears holding sickles plays the classic metallic song Abracadavre.

In updated releases like Call of Duty: Black Ops III, players can also trigger alternate audio tracks by interacting with ringing red telephones. These subtle audio details offer a fun break from surviving endless waves of the undead.

Radios and Environmental Lore

Scattered throughout the cosmodrome are hidden radios that broadcast recordings detailing the story behind the facility. Listening to these audio logs reveals critical background information about Dr. Gersh, Yuri, and the events leading up to the outbreak.

Observant players can also spot visual easter eggs, including subtle nods in the loading screen art and hidden character details. Taking time to explore the environment reveals how much care was put into expanding the overarching Zombies storyline.
