Hey everybody! I decided to make a guide for PJ 1 since i think there are people who want to 100% complete PJ 1, but either bad or don't know how to.
So let's get started.

I'll be describing animatronics first in a night order, and only after that strategies for all nights.

Guston - actually a big threat. He will go to your left door. once he is there, for the first time you flash him he will go right to the doorway, but won't attack, unless he has a movement opportunity. The main problem is, you can't see him with the door closed, so you have to either count to 10 in mind(he usually goes away by that time on max AI) or look for him on Stage and Dinner room cameras.

Tisi - much easier than Guston. He will go to your right door. If he is near the door, it is not closed and you are viewing cameras, after pulling them down you'll see Tisi trying to get into your room. Instead of Guston, Tisi is visible in a window even after closing the door. To defend from both of them, you'll have to close doors on them.

Lucas - a bit harder enemy than Tisi. He will go out of his cove and eventually run to your left door. I don't really know if you can stall him just like Foxy in FNaF, however Lucas isn't that much of a problem. After hitting your door, Lucas drains 3% of power(8% on insane mode).

Joaco - one of the easiest enemies, even though you have to pay attention to him. Every time he moves, he will make a laugh, that will get louder the closer he is. He moves to either of the doors, however will make a panned to the side he is laugh. At that moment you have to pay attention on his eyes, if they are glowing, you have to use door light on him, if he is eyeless then close the door. If you are making the wrong action, he will kill you, even if both your doors are closed.

Leandro Endodro - really simple, but quite annoying enemy. He will go through ventilation system, that you can look at behind you by pressing S key. Sometimes, when he moves he can disable you ventilation, requiring you to turn it back on. If temperature gets to 120, you are dead. If Endodro is 1 move away of getting to you, you should close ventilation seal and eventually he will hit it. If Endodro is 2 or 1 moves away from you, ventilation seal won't open until either you open it or Endodro hits it. On high AI levels, he will turn of ventilation almost every movement.

Now we are going to secret characters, so spoilers alert!

Shadow Joaco - an INSANELY annoying enemy. He will always be behind you, and fastly show up if you look back, however turning around will reset him. If he fully shows up, you are as good as dead. The other way he can attack you is by appearing after lowering a monitor. All you need to do is to pull cameras back up for at least a frame. However Shadow Joaco can appear several times in a row, so be ready for him.

Mister - pretty easy enemy. When he attacks you, his face as an icon will appear near cameras. If you don't open them, you will die eventually. After opening cameras he attack you in 2 different ways, via doors or vent. If he attacks you via doors, he will show you a sign showing where he will attack, all you need to do is just to close door he is attacking. If he attacks via vent, he won't show up on cams, however after lowering them, you'll see a guy showing a sign with word vent and you'll hear someone running in the vents. To prevent death, you have close vent seal, however because of Shadow Joaco, you'll have to time it that way, that when you close vent seal, Mister will knock on the door and you won't die to Shadow Joaco.

Ghosts - they are just annoying. One of them will appear on cameras, you'll just have to close cams to prevent him jumpscaring you. Another will rise on your left, you have to pull cams up to prevent jumpscare. The last one will sometimes appear on your table after closing cams, you have to click him before raising cameras or else he will jumpscare you. If they jumpscare you, you won't be able to use cams for some time. If you get jumpscared by a table one when there is Shadow Joaco, you'll die, as cameras aren't open even for a frame for him to leave.

Now let's talk about strats for max modes.

7/10 - isn't really hard. All you need to do is just check doors, check Endodro and be aware of Shadow Joaco.

Insane mode - this is actually hard now. This is the night, where ghosts appear. This is basically 7/10, but after every camera flip click on the table ghost spot to prevent death from Shadow Joaco.

All challenges - this is REALLY hard. Shadow Joaco is A LOT more active than in 7/10 or insane mode and will a REALLY high chance of reappearing after dealing with him for the first time. Now you also need to deal with ventilation system ass temperature is rising insanely fast. Ghosts are also present here, and are around the same activity as Shadow Joaco. When i finished that night, i had around 5% of power left, however that was before Joaco's bug being fixed, so you might be finishing the night at blackout if you are on the last version.

Endless night - nothing to say here. Infinite night, with enemy's AI constantly rising. Just try to survive as long as you can.

Hope this guide will help someone to beat max modes!
