I'm not gonna act like I know the ciphers or how they're solved (he explains it, but I'm dumb and a bit drunk rn) but this kinda ties more of the bow with the BOIII storyline and provides a bit of an epilogue. Purpose of the post is to provide the solved ciphers.

Rev 10:

With the blood secured, Samuel, Russ,man, Abigail and Marlton have been taken care of permanently. I buried them under the island prison below the lab. Noone will ever find them. Not even Monty. There is not much time left. R.

Rev 2: (Added puncutation myself, wasn't part of the cipher in the video.)

Samantha finally left the house today, she was the last one. I understand how hard it was for her, but she knows this world is big and beautiful and needs to be explored. I am sure she will see the others along her travels. Honestly, I will miss her. The most I must admit it looks like I am not needed anymore; retirement here I a come. It's time to pack up all the chalk bozed and machines and go behind the scenes, go to that God-damn white sand beach I have thought about for ages and chill. I mean nothing can go wrong. No signing off [unsolved portion].

(Skite Innit assumes it ends by saying "Doctor Monty")

Rev-5:

August, 1946. OSS final T-7. All of the Group 935 and Division 9 facilities, we were able to procure have been dismantled and cratered. We have 315 scientists heading back to the United States for Orientation.

July 1947. OSS asset transfer request. We are requesting that Dr. Shuster be transferred to Broomstick and the Titan Project because of extensive intimacy with Group 935's long range rockets. If approved, we will have him onsite at White Sands for the first Titan Project test as an observer. As you know, it is imperative that we advance Titan quickly and reach the anomaly before the Russians.

Rev-6:

Oh zombies, what will we do when your gone. Life without you will be dull. But it is time to go somewhere and sing a new song.

Rev-8:

FInal Entry: I have run out of pages for this journal so it seems fitting that this is my final entry. I am leaving the hosue today for good, and I don't think I will ever return. Father has been gone for many years now, and I will miss him. I think of him often. Monty says he is not dead but has just evolved into a new form. I guess you can say that Monty is my father now, really the father to all of us kids that grew up at the house. We know the sacrifieces that were made to get us here and keep us safe. I will always love them for that. A debt that can never be repaid. Monty was going to take me to the lake today to go swimming. I love floating in the water with the warm sun dancing on the surgace and watching the clouds slowly pass overhead. Sometimes I think I will see father in those clouds looking down at me and I smile-I know he will always be with me. Samantha.

Rev-9:

"My love we are now flowing among the stars, among creation, as one. I love this feeling. Me too. Where shall we go. Everywhetre my love … Everywhere."

Rev-12:

Now that the many worlds are one, it has all reset. There are no Apothicon, Keepers, or 115 knocking around to cause trouble. Now I can focus on the children, making sure they grow up in a better place.

There's a lot to this, but I'll talk about it in the comments since I don't wanna cloud the posts and focus on the quote here.

There are 3 ciphers remaining in Revelations.
