Probably been suggested, but I haven't seen it yet, so:
I was thinking, I believe that 513 itself causes a memetic effect that makes people see 513-1 unless I've read wrong, that when you find 714 there should be a note saying something creepy along the lines of "Always wear green" or something, to hint that the player keep 714 on at all times, because after one picks up 714, 513's noise is triggered over the intercom at a random point later on, no earlier than 5 minutes and no later than 30, being rung probably by someone in the insurgency trying to destroy the foundation. If the player isn't wearing 714 when 513 is rung, they will see 513, and after an hour of gameplay or so their vision will blur and they will eventually die or be rendered unable to move on their own because insanity literally drove them into hiding in a corner. Then 106 could come and kill you or something just to keep from prolonging the game, and a special message is shown on the YOU DIED page to at least inform the player of what happened to them so newbies dont come to the bug report section like "WTF happened?". Thing is, 513's randomly timed noise can only occur if someone picks up 714, giving them at least a chance to survive. Just a thought. There could maybe even be an achievement at the end like "Used 714 to block 513's effects."
