The Moon Base

The Lunar Base is the Nazi research facility on the Moon in Wolfenstein: The New Order (2014). After Blazkowicz and the Resistance hijack the U-boat Eva's Hammer, they find that its nuclear cannon needs keycodes held at the lunar facility. Using the Spindly Torque, a spherical Da'at Yichud device that can destroy super concrete, Blazkowicz steals the identity of a Nazi lunar scientist and infiltrates the base. He gets the keycodes, but on returning to Earth he finds that Frau Engel has attacked the Resistance base, killed several members and captured the survivors. The game ends with the Kreisau Circle pulling a badly injured Blazkowicz out of Deathshead's fortress and destroying it with that cannon.
