When the compass headgear is now examined, it will tell you the
direction your character is facing (north, south, east, or west). This
only works when you're on a planet, this means being groundside and not
on a map that is situated in space.

I've considered changing the description, but I've left it because I
couldn't think of a better one.

# Explain why it's good for the game
When I used the compass in game, I expected to actually tell me which
direction I'm facing, but I was a bit disappointed when it didn't. So, I
change it to work in a realistic way.


# Testing Photographs and Procedure

On LV-624, where the compass works (left). On the ship, were the compass
does not work (right).

On maps like Fiorina where are situated in space, the compass will not
work.
