The Hololive Incident 3 (V1.5.2)

In this mod, "The Hololive Incident 3" (also known as "Incident at the Detective Headquarters"), you play as Mano Aloe. While walking home, you receive a phone call from Bolder (BBTOL CH.3) who explains that he needs your help to fix the SCP security cameras as he is busy. Once you collect a Detective book, it will teleport you to the security cameras where you will encounter simple math questions. (Note: in the upcoming version v1.5.2 that I am currently working on, the math questions will not be as simple as those you encountered in the game.) Gather all 7 Detective Books, and then you are free to go! However, be cautious about what you do with the SCP security cameras.
