Notes

(insert number>=9) characters
Scout: He will start in his room eating chicken, when he isn't in his room, then try to look for where he went to, if he's in another character's room, that character will now come for you. If he is in the hallway, close the door quickly, he is fast and will use his legs to run down the long hallway and make you lose if you don't. If you use the disguise kit, there is a 50%chance he will fall for it, and 50% chance he will get you anyways.
Soldier: He will be talking to heads until he hears something loud (like demo's charge) and will come to your room to check, use you're disguise kit to fool him, if you don't, you lose.
Pyro: Pyro will be watching tv in the room right next to you, if he stares at the camera, then he will come in very soon, if he comes in you will have to change the channel in his room for him to go back. He would never ever fall for any disguise..
Demoman: AAAAAAAAAAAAAAAAAAARGH, he will charge down the hallway and enter your room, shut the door when he comes, if he gets in you lose, he cant move while the cams are on. He will drink all of the (imaginary) scrumpeh (soda) in his room and when he does, he will charge shortly after. He is on a sugar rush so he won't even notice if you disguise.
Heavy: When he gets into your room, find Natascha, then he will leave, if you don't find it, you lose.
Engineer: Engineer is relaxing in your room, when he stands up, you need to either look at cams or use the disguise kit, if you don't he will start draining your power and make a lot of noise doing so, either that or he builds a teleporter and sniper will come through.
Medic: Medic will not fall for the disguise, when you see him outside of his room, he is either making another character stronger or he is coming right to your room and you will need to close the door or you will lose.
Sniper: He only appears when the Engineer builds a teleporter, he will walk out of your room to give you a chance, when he is right outside your door, HE WILL NEVER LEAVE so close the door, the only way he would leave is if spy appears next to him. Spy: Once he gets in your office, you can't use the cameras until he leaves, he will leave in a set time or if pyro comes. Use the disguise kit to make him think you're someone else.
