Main Quest / Ascension

Casimir Mechanism

Ascension’s Casimir Mechanism is where the main quest was invented — the first multi-step group Easter egg in Treyarch Zombies. From round one Gersch pleads through the speakers to be freed from the mechanism before "she" arrives; five repair nodes later, a black hole fed with wonder-weapon fire lets him out. It strictly requires four players (one node needs four buttons pressed in the same instant) and, unusually, awards no achievement — the reward is ninety seconds of Death Machines and a debt repaid later in the story.
