Description

based on modern times, arc-524 is a facility notorious for operating with minimal supervision under the o5 council. located in a valley somewhere in the northern hemisphere, the exact location is unknown. grueling and extensive "ethical" testing occurs on-site on the many anomalous subjects inside. arc-524 takes place in scp universe 39c, with many notable differences from the source content. the individual holding the title "the administrator" does not exist, and the o5 council only exists as 9 regional overseers, and there is no o5 head. disclaimer: this is primarily an xbox scpf, meaning we don't advertise to pc players as our main focus, they can join we just don't ask for them directly to. secondly this is very inspired off of arc-478 a popular pc scpf on roblox, the idea, groups, and department ranks are based off of arc-478. if you are on pc and looking for a great experience, please join them. founded by lostshawnzy heavily inspired by [arc-478] secure. contain. protect
