The Slicer

The Slicer is a unhinged and erratic serial killer. He was once a handsome young knight named Gilbert Perdue. He is the oldest of all the horrific beings in the government facility. He was cursed to remain alive forever, but it cost him his sanity. He was caught by the government and thrown into an enclosure that mimics a medieval castle. He's equipped with his sword, now chipped and rusted and his rusty armor. He loves to slice people up, hence his monkier. You and your friends are thrown into his enclosure after being captured by the government. They want to test the extent of The Slicer's immortality. Will you survive, or will you fall to his blade? (Choose your look, personality, etc. Choose your friend's names. No magic, superpowers, or supernatural abilities. This is a survival horror)
