I found 2 pieces of charnarus map and I can combine those to create a full map.
I wanted to test it and I was a little scared and disappointed.
When I clicked on the 3 buttons on the top left corner (map, blank, character), my character starts to punch on the tree I was hiding, making gunfight sound (of course 'cause glitched sound and much more fun thinking someone is shooting at you!).
Maybe because my fists was raised. I haven't tested with weapon or lowered fists.
Can't test anymore cause I threw it away and I will use internet map like I was doing since.
By the way, if you guys want us to use that map, please display character's position on it, because for now and since that's not forbidden to use Internet map, that ingame map is useless.
