Call of Duty: World at War
In Call of Duty: World at War, a squad of USMC soldiers fought against zombies in Nacht der Untoten and Verrückt. Tank Dempsey led the team of Marines to Verrückt to extract undercover operative Peter McCain, whose handler believed was compromised, and resulted in almost all of the team's death; only Dempsey survived. After Verrückt, Dempsey made it to Shi No Numa and Der Riese along with Nikolai Belinski, Takeo Masaki, and Edward Richtofen.
