Season Four Reloaded of Call of Duty: Black Ops Cold War Zombies casts players into Mauer der Toten for an Omega assignment set in Berlin, with the ever-growing threat of an undead horde. If you find yourself in need of a better loadout but don't have the Salvage for a Tier Upgrade, consider unlocking the free Aether Tool.
The Aether Tool is a one-time use item which will give an immediate Tier 5 Damage upgrade to your current weapon.
