Check three things: you are Coherent (the effect icon is showing), the door is shut, and the Box passes its
check (sneak and use the door with an empty hand). Then stand still for five seconds. See
Building the Box.
I can't pick the Pale Lotus.
It only opens at night, and a closed flower breaks into nothing. Come back after dark.
The Cryo Stabilizer stopped.
It needs packed ice or blue ice touching one of its sides (or a coolant poured in). Without cold it pauses and keeps
its progress.
The Centrifuge won't run.
It only takes plain water bottles. Any other potion stops it.
I keep sliding sideways and feel sick.
That's Decoherence: you dosed again within 5 minutes of your last dose. It wears off after 5 minutes, or drink a
Steady Draught.
My Serum ran out in another world. Am I stuck forever?
No. Check the arrival Box for its Serum cache, look for the world's native stand-in for a lab ingredient, and brew
more. No world is a dead end. See Stranded.
How do I find my way home in the Corridor?
You first arrive facing the home door, and in the default lenient mode it glows. Mark your path with chalk.
Which world is behind a door?
As a door opens you glimpse what kind of world is behind it. A door always leads to the same world, so mark the ones
you like. Doors close to home lead only to Calm worlds and worlds with Strange physics.
Can I play with friends?
Yes. Everyone who is dosed and inside the same sealed Box crosses together, though each traveler walks their own
Corridor. Everyone who comes to a world arrives at the same arrival Box.
Where are my quests?
In the Traveler's Guide, and the compass at the top right of the screen points to your next objective (J hides it).
