Ruthlessness Is Mercy Upon Ourselves (Reader Insert)

It's been about a decade after getting a head injury, which caused you to forget about your old job at Playtime Co. But then, you've received a letter telling you that your supposed co-workers from Playtime Co. are still there after 10 whole years. You didn't tell your parents about the letter, and later found out - through research - you that you used to work there, but after an accident happened when you were coming home, and just so happened to get in-between the crossfire is when you got your head injury. Against your better judgement, you went there because of your growing curiosity and sudden rise of internal guilt rising inside of you. You made a promise to your little brother that once you return back home, you'd give your little brother a toy from the factory as a souvenir.

How will you survive this madness that'll stand before you in your expedition? Will your little brother be enough to convince you to move forward and survive this hell that was bestowed upon you; your will to not give up just yet? Will you fight against the Prototype and live in the end? Or will you end up dead just like the rest of Playtime Co.'s staff?
