The story of Snowbreak: Containment Zone is set on a post-disaster Earth, beginning with a catastrophic event known as the "First Descent" in 2057. During the finals of the popular Valkyrie Games, a gigantic being of unknown origin, called a Titan, smashed into the stadium. This Titan, named Ymir, disappeared but left behind "Titagen," a snow-like pollutant that forced the mega-corporation Yggdrasil Enterprises to wall off the contaminated city, creating the first Containment Zone Aleph. The plot picks up three years later, following the Adjutant, a Yggdrasil officer who crash-lands in the center of Aleph after a three-year mission in space, missing his memories from that period. He is quickly promoted to lead the Heimdall Force, a paramilitary unit composed of "Manifestations"—humans who, through various means such as contact with Titans or a specific medical treatment, have gained the powers of mythological gods
