To get the 'Good' end in FNAF: Into the Pit, you'll need to complete a few special prerequisites, including fixing all of the arcade machines. Doing so will also get you some achievements. Repairing each of the arcade games can be a pretty difficult task, but it's made easier if you know what parts you'll need for them and where to find those. Here's how to fix all of the arcade games in Five Nights at Freddy's: Into the Pit.
How To Repair All Arcade Games In FNAF: Into the Pit
Night 1 Arcade Machines
There are eight arcade games that you can repair on Night One. Most of the arcade games will be found during this night, and fixing them will be much of the focus of your day.
Each one requires a unique item that can be found in a different area around the environment. Some arcade games have hidden parts, while others can be more easily found by looking throughout the pizzeria.
Heftin' With Helpules
To repair this arcade game, you'll need the Weight Resistance Mechanism found in the Home Basement in the Present.
Solve the Puzzle
To repair Solve the Puzzle, you'll need the Puzzle Matrix, which you can get from the Mill during the Present.
Collect the Hats
Fixing this game requires a Control Panel from the Pizzeria Party Hallway in the Present. This isn't the only part you'll be able to find in this room, though.
Deliver the Pizza
If you want to boot up Deliver the Pizza, you'll need to replace its Power Supply by grabbing one that's been thrown away in the Pizzeria Party Hallway during the Present. Be sure to check the garbage cans to find this somewhat hidden part.
Shoot the Space Balloons
The owners of the Pizzeria have apparently left tons of stuff in the Pizzeria Storage, so check it to find the Electron Gun in the Present.
Fast Food Invader
You'll need a space-themed part for this space-themed game; who whould've guessed? Grab the Space-Age Speaker from the Pizzeria Arcade during the Present to fix it up.
Pizza Roller
To play Pizza Roller, you're missing the Wooden Balls part from the Pizzeria Ball Pit in the Past. How did those get there?
Rescue the Children
To get the Token Slot and play a round of Rescue the Children, you'll need to find the Token Slot in the Pizzeria Basement during the Past.
Night 2 Arcade Machines
You had to repair a lot of arcade machines on Night One, but take a breath of relief knowing that here's just one arcade machine that you can fix on night two: the Prize Machine. However, that leaves only one arcade machine left!
Prize Machine
To fix up the Prize Machine, you'll need the Voucher Validator found on the second School classroom in the Present.
Night 3 Arcade Machines
On the third night, you'll fix up the Ticket Counter, your final arcade machine. Once you've repaired it, you're all done.
Ticket Counter
To repair the Ticket Counter and finally start earning stickers, you'll need the Ticket Counter part found in the Pizza Dining Area during the Past.
Now, you've repaired all of the arcade machines in Five Nights at Freddy's: Into the Pit and earned yourself an achievement! You should pat yourself on the back, as you've now satisfied one of the most difficult requirements for getting the game's good end.
