"Can I 100% COMPLETE the HARDEST Five Nights at Freddy's FANGAME ever made (Post Shift 2 Pre-Patched)"

After completing Post Shift 2 in its pre-patched form, Chickeninja42 went back to 100% complete the game. To start, he notes that 100% is completed by taking 4 routes, collecting 6 items, completing 24 objectives, and finding 8 secrets. Already having the six items and all 24 objectives, he also had one route and 3 secrets, leaving three routes and five secrets to collect.

Since he had the Good Ending, starting off, he notes how he can quickly get the Bad Ending by playing through the game again without collecting items or completing end-of-night minigames. In Night 1, he discusses the map and Nights 1-3 objectives and explains the mechanics for Minater Freddy, Revenant Freddy, and Minater Foxy. Skipping the house segment after Night 1, he goes onto Night 2, which is the same as Night 1, but adds Revenant Bonnie and Minater Baby, whose mechanics he explains. Continuing to Night 3 adds more animatronics again, this time being Remnant Chica and Remnant Foxy, whom he explains. Then, he shows some failed attempts.

Night 4 is the first of the different nights in Part B of Post Shift 2, as Nights 4, 5, and 6 take place all in different locations. In Night 4, he explains Minater Baby, Minater BB, Minater Ballora, and Minater Freddy in the Simulation Monitor first, followed by describing virtual discontent, then Minater Puppet (and Venta Puppet, whom she spawns), Remnant Puppet, Remnant BB, and the Minatereenas, aloongside the surrounding activity. Afterwards is another series of failed attempts.

Night 5 is once again in a different location, and where the game becomes especially luck-based. He explains the Insta-Order objective, followed by the four animatronics: Subject 01: Freddy, Subject 02: Foxy, Subject 03: Chica, and Subject 04: Bonnie. Following is another attempt montage.

Night 6 is the most difficult and complex night out of Post Shift 2's main nights, having four segments overall. Nearly every animatronic returns this night, and few of them have the same mechanic. From 12 to 2 a.m., the four subject animatronics from Night 5 return. From 2 to 4 a.m. are Revenant BB, Minater Puppet, Minater Baby, Revenant Puppet, Minater BB, and Minater Ballora. From 4 to 6 a.m. are the Revenant and Remnant versions of the main four animatronics. After is a 200-second run with Revenant's End and Emalgabot, both making their first appearance. After every segment, Subject 05: Golden Freddy shows up. He discusses each segment in order, alongside the animatronics' new mechanics. He notes in segment 1 that it's also supposed to have Shadow Freddy, but he's bugged and doesn't exist in the pre-patched version. After 4 a.m. and after 6 a.m. are checkpoints to assist in the 12-minute long night, especially since Revenant's End and Emalgabot both have multiple attacks and a new area is added during the final 200 seconds. Another montage, and the bad ending is complete.

With the bad ending done, he starts to set up the rest of the collectibles. He starts with the secrets before going to the harder bonus nights. Bonus Night 1 is Night 4, but every animatronic has more aggression, making Revenant BB especially difficult, and nigh impossible with Minatereenas spawning as well, turning the least RNG-based night into a very heavily-based one. A montage leads the video into Bonus Night 2, a remaking of Night 5 with constant limited oxygen and the incapability to open the control panel while using the oxygen mask. This makes the end of the night especially luck-based, as the Insta-Order can easily cause you to run out of oxygen. A penultimate montage including an apparent bug before Bonus Night 3, a Night 6 with the only difference being the length is doubled, making it now 24 minutes long and forcing attention to the power and oxygen. Since the elevator in segment 4 disallows usage of the monitor or gas mask, moving there for an attack could easily cause a loss by oxygen leak. However, another checkpoint is added at 2 a.m. to balance out the length. After one last set of attempts, a third route and another secret is obtained. Waiting two minutes leads to another secret, and another thirty seconds leads to another. The next cutscene gives the last route and last secret, completing the 100% of pre-patch Post Shift 2, and Chickeninja42 ends the episode.
