you can say EVERYTHING, but I spent over 200 hours looking for stasis rope alone after I chucked it. Not coming back to me anytime soon. Plus, I already got pissed and made a new file where I traded off the stasis rope to my good file through the use of one of my friends. After you actually succeed on a mission, I don't think it comes back unless it is a repeatable one.plus, the game reccomends and tries to advertise trading and linking up with other people who have the game, so nothing is ever unsolvable. It could just take a VERY long time.
