It's 1962 and the Cold War shows no signs of cooling down. A new Soviet bioweapon called Project MEDUSA threatens humanity, and the CIA needs capable people to stop it. The recruits, though, aren't seasoned spies in suits — they're fresh medical graduates. Swallowed by disguises and fake documents, you travel the globe using carefully constructed aliases, jumping between allied, neutral, and Soviet-controlled cities. Your mission? Neutralize enemy agents, secure specific targets, and position other CIA operatives on site to run operations without a hitch. The game unfolds month by month over twelve rounds. Each playthrough introduces new elements — new cards, rules and conditions that reshape everything that follows. Your characters grow: aliases gain contacts, assets and abilities that smooth the path in later rounds. But watch out: things can go wrong, and mistakes pile up. The board changes, the plot branches, and what you did (or failed to do) in the previous round haunts you. The tone is a spy thriller with the tension of Pandemic — except instead of openly fighting a virus, you do it between secret messages and agents who need to quietly disappear. You don't need to have played Season 1 or 2; Season 0 stands on its own. But if you already know the Pandemic Legacy family, you'll recognize the magic: components that are never the same once you crack open the box for the first time.
