I am trying to play this game but am stuck on the first chapter! I have gotten to a place where you have to put a code in to a keypad to unlock a gate on the train, but don't have an f-ing clue what it is/where to find it etc etc.
Am I being totally stoopid? (Don't rush to say yes please!)
Anyone know what the code is or what to do to get it?
I have spent 20 mins trying to google walkthroughs to no avail!
