Operation Ragnarok sends agents into the Swiss Alps to infiltrate a secret summit hosted by Nýr Jötnar, a wealthy and disciplined doomsday cult preparing to unleash global catastrophe. Under deep cover as event staff, the team must move through an isolated mountain estate filled with security personnel, loyal followers, hidden chambers, and guests whose influence reaches far beyond the party walls.

Inside are mission briefings, timed plot events, detailed maps of the estate and underground laboratory, major NPCs, enemy forces, and multiple paths to success through espionage, sabotage, deception, extraction, or direct assault. As the night unfolds, agents uncover the Einherjar Virus, captive test subjects, secret financiers, and a self-destruct system capable of burying the truth beneath the mountain. Operation Ragnarok is ideal for campaigns centered on cult conspiracies, biological terror, undercover tension, and cinematic missions where the world may end before sunrise.
