[TOMT] [facebook arg] please help me find a video covering this arg

I'm pretty sure it was posted by some sort of youtube channel like nexpo that covers internet mysteries, not sure which one. i'd say it was posted maybe two or three years ago? im not very sure on that.
it was a video covering a facebook ARG where girls are being used as expirements to create superhuman soliders (i think it was implied they were in another world?? maybe. im not sure.) it started with one of the girls messaging somebody on facebook, then escalated into the users helping the girls escape from the facility they were trapped in. i have honestly no clue how i can search this up, and i dont know what the arg was called.
