Chaos included!
Delay the inevitable end of the station with (or without) the help of your crew
You're joining the crew of a lunar station. There's no single objective — you explore, you keep the lights on, you help (or mess with) your crewmates, and you figure the rest out together.
It's a top-down, tile-based multiplayer lunar station. Walk around, open doors, keep the air breathable, and talk to whoever else is online. What happens next is mostly up to your crew.
The station sits at the floor of an enormous lunar crater. Open the right door and you might vent the station's air supply into the vacuum of space. Open the wrong door and you might find yourself staring at a wall of fire. Or a fellow crewmate, who may or may not be friendly.
The moment you join, you're randomly assigned one of eight crew roles and handed the matching keycard — your ticket through any door (of the same color). Some roles even come with special items used to perform their day-to-day duties.
Rooms hold their own pressure and gas mix, and it leaks out through any gap to the outside. Seal the hull, or run an O2 generator and CO2 scrubber to keep a room livable.
Locked doors tell you exactly which color you need — hold a (legally obtained?) matching keycard to get through.
Doors, consoles, and alarms all run off generators. Cut the power and everything downstream goes dark.
Drag a mining drill onto the lunar dust, keep the drill's battery charged, and tow your haul back home.
Climb ladders to move between decks. You only ever see the floor you're currently standing on.
Explored areas dim like a memory when you look away. You may not know what's lurking in the shadows.
Dead? You're now a ghost who can trigger faults in the systems present on the station.
Tranquility Base is self-hosted — there's no central server to log into. To play, you need two things from whoever invited you:
7777 unless they say
otherwise).Open the game, choose Connect, enter those two things, and you're in. The Player Guide covers everything from there — controls, your role, your inventory, and what to expect on your first walk around the station.
The full guide walks you through controls, roles, and your first few minutes on the station.
