Signs

Summary
Signs have been recently added to Floor 1, meant to guide players, give hints, or possibly, throw them off. Every sign requires a certain level of Knowledge to be read.

Floor 1
The signs on Floor 1 are hints for newer players on how to solve the floor. With the exception of the sign next to the Floor0 portal, which says "family is above."

Floor 2
On Floor 2, there is a single sign in the spawn, which says U-Boat, Enigma. Multiple people have concluded that the sign is referring to the Enigma Machine, and it is either trying to throw us off or a genuine hint for a future floor.

Trivia

 * The first sign added was the one near the spawn at Floor 1. The others were added at a later date.
 * The floor 2 sign was confirmed to be a red herring.
 * The floor 0 portal sign was originally "coming soon" before it was actually released.
