Amnesia Multiplayer (Cringe as you may.)

[ZyLogicX]

I have actually been thinking of implementing some sort of 'multiplayer'-aspect into a custom story. You and your friend have 2 different maps, a puzzle for player 1 can only be solved by communicating with player 2.

Concrete:
Player 1 comes to a locked door with a 4-digit code. Player 2 (in another map) has to find a way to help player 1 by exploring his map. Eventually, he finds a note with the code. and vice versa.

It might sound easy, and a lot of trial and error can occur. But I do believe some creative minds could make something brilliant
