SCP: Dead Letter Protocol

Your job isn't to win. It's to decide what you're willing to lose.
Beyond any government's reach, a secret organization contains the most dangerous supernatural threats on Earth. Things that could reshape reality, corrode sanity, or destroy entire nations if they breach containment. You just accepted a position you can't quit.
Choose your apocalypse. Every scenario pits you against a different existential threat. Investigate anomalies, contain creatures, and make morally questionable decisions as entropy tears your facility apart.
You Don't Know What You're Fighting
Every creature starts with it's details hidden behind ████. You don't know its name. You don't know what it does. You don't know how to hurt it. Your loadout locks before the fight begins. Match the creature's hidden vulnerabilities and your weapons tear through it. Choose wrong and your best gear does almost nothing.
Study a creature to reveal hidden traits. Talk to it through branching dialogue that can expose weaknesses or make things worse. Contain it, destroy it, or flee. Every path is viable. None of them are safe.
Creatures you contain are documented permanently. Every trait revealed. Every vulnerability exposed. The next time you face it, you'll be ready.

Four Phases. One Is Yours.
Reinforce the breach or pursue the objective. Recruit an ally or stockpile for what's coming. Spend the round investigating or pray that ignoring the anomaly doesn't cost you the mission.
Your Turn: Three actions. A dozen emergencies. Something is always getting worse while you deal with something else.
Encounters: End your turn in any location to face unique narrative encounters. Resources, allies, items, improved abilities. If you make the right decisions.
Anomalies: Every round, they count down. At zero, they become greater threats and start roaming the facility. Some hunt you down. Some damage the facility. They don't stop.
Entropy: Quiet at first. Until it isn't. Lockdowns seal off entire wings. Failures cascade from one system to the next. At 100%, the scenario's final threat arrives. It doesn't care how prepared you are.
Every decision costs something. Every round, the list of things you can't afford to lose gets shorter.

Between Runs
New operatives and scenarios unlock, expanding the encounters, creatures, and crises the facility can throw at you.
