I've been working on my Expanded Access mod (seen here) and am putting up some signposts with messages. I've figured out the symbols for the up, left, and right arrows, but can't find the down arrow! Is there a list of these somewhere?
There are no down arrows in the game. The arrows are used on signs in-game to direct the player to locations, but there are no signs that direct downwards. You would need to edit it in yourself and replace a different symbol.
