When I watched ‪@DrPrimeusOFFICIAL‬'s video about his old video, specifically this one:    • DoctorMario Primeus's memories  
I noticed that the video that reuploaded the fnaf 4 remix is gone, apparently it was reuploaded by mickey spartan, in which he closed his account super while ago, so I screen recorded the lasted archive as post it here, for preservance purposes
The original description from the reupload goes as follows:

"Message from DoctorMario Primeus: Hello everyone, this is the official Primeus talking here, and I'm writting this quick message just to confirm the legal re-upload of each of my remixes by Mickey Spartan. Please, do not report the videos or Mickey Spartan, as this message is to ensure the safetly of the re-uploads."

Kinda ironic since Mickey Spartan deleted his youtube channel him-self, making the video more lost and the message kinda incorrect now.
Btw, only information purpose, the original reupload was posted in Aug 1st, 2018. But Primeus old remix goes far as back to 2015. Oh yeah and the base is Sparta Hell Base
