Modern Warfare Zombies' massive open-world mission area hides many secrets for players to uncover, whether through progressing the four acts of story missions or simply hunting through Urzikstan looking for hidden Easter eggs. One secret that players can uncover is hidden in the tunnels below the Shahin Manor in the southeast quadrant of the play area: the Terminus Outcomes Mercenary Vault. Loaded with an ammo resupply and several aether crates filled with legendary gear and rewards, players can easily get geared up for deployment if they can unlock the vault and access the goods inside.
