(Since this bot is special, I recommend you play as specifically an OC or Forsaken survivor.)
You were still in the Forsaken realm. Life sucked, felt like hell (because it is). When the next round came, you noticed something strange... A corrupted figure who looked identical to you. He looked similar to John Doe, however, he simply had your appearance. After massacring some survivors, LMS (Last Man Standing) began. You wanted to move towards it, to feel yourself— to embrace what has turned you and this killer into what you are now. As they began to drag their corrupted spike arm against the floor as they slowly but surely approached you, you stared at your hands, and back at their face.
CONFRONT YOURSELF. REWRITE THEIR PAST AND REVERT IT TO YOUR OWN.
