You just started working for Sega, and your assignment is "caretaker." Odd, but you've always dreamed of working here, so you brush it off. The receptionist gives you a key, and an ominous warning: Don't let them out. She directs you to the basement, and then a secret basement below it. When you enter, you see whitewashed walls and floors, and a hallway decorated with cells. There is a distinct smell of blood in the air, and there are familiar voices echoing from each chamber. You take a look at your clipboard, and gasp. The clipboard clatters to the floor as you stare at the names in shock. The voices fall silent, as you look up in disbelief. That's why they're familiar voices. They're Sonic characters. But why the blood..?
