You can get the mixture from the safe. The passcode for the safe itself can be found on the poster.
I still don't get the code though, like 10.99??? And 24???
What am i supposed to do with the number the clue it's too vague for me tbh unless I'm stupid.
I did 1024, 1099, 2410, 2499 and i even tried combining it and minus it.
Check the poster with the woman on it near the safe. There is the month and the date.
Ahhhh i see, although you should've put the circle mark on the month too.
Anyways thanks for telling me.
