Mos operating system (consumedByTheDarkness)

explaination : 

yesterday while cave-diving, i came across a floppy floppy (floppy disk) that strangly had ketchup and the "mos" on it.

instantly, it reminded me of when i came across a numerous amount of creepypastas with the same stuff with blood having something spooky

so because i was intrigued, and my childhood dream coming true, i took it home, exported it, and i was met with an exe applications with the name "mos". when running it, i'm met with an error saying "map1.3ds file not found".

i figured out that renaming a file ironically "DON'T RENAME.DON'T" to what its supposed to be names and barabing barabong! into mos we are

and well.. this is where you come in!

try to find out what secrets this mysterious file hides within its binary wizardly!
