OK, I am in the Naxos Prototype mission, and I cannot, for the love of god, figure out how to "show my papers" to the german guard that asks for them. I press the use button asuming that it will use the item, but alas, nothing ever happens, eventually the guard gets pissed off and shoots me. WTF am I supposed to press so I can show him my damn papers?
They call that little book in the box, the instruction manual. Unless of course you didn't get an instruction manual with a version you downloaded off the internet?
and then you should never have to worry about it...
but.... ...if you want to make it more interesting,like I did, just use your silenced pistol - either to shoot him or just knock him on his head 3 times to kill him(not noisy) - then holster your weapon and walk away... problem solved... hehe
