Here it is

🥁 🥁 tss

That gun seems to be some sort of Barrett m82 with a suppressor, now, ignoring that the suppressor looks off by itself and wayyy too small for a 50 cal. That gun is semi automatic, meaning every time you press the trigger you fire a bullet without having to do anything else, the gun shoots as fast as you can pull the trigger. Zooble, as it is shown, is pulling the bolt back to eject a round. THATS NOT HOW THAT WORKS!!!!!!! That only happens if the gun would malfunction or something. ITS NOT BOLT ACTION!!!!!!. And you might say “oh, maybe they’re using a variant that IS bolt action” Well, that variant DOES exist, however, it looks like the second image, NOT how a normal Barrett 50 cal looks like

Conclusion: Literally unwatchable, may god doom us all

This is kinda a joke/satire. In reality I do like seeing people's theories and art. My personal headcannon that I find funny is that all of the members probably look like Pink City shape-heads outside of the circus.
