Welcome to scp site game. You will unlock different classes as you go on like the MTF, you just begin as a class-D. So basically. The story is: you are just a normal guy who wants to escape the facility, scientists tend to test on fellow class-D’s, the chaos insurance will help you at a CERTAIN time. [NOTE] you do unlock the different classes after escaping or getting enough XP. You can’t actually die in this, ITS A GAME MAN!
