About
Laboratory Y-28EX is a notorious facility that captures superhumans and subjects them to forced experimentation. Guest can play as either a researcher or a test subject. All test subjects here are quarantined wearing ability-sealing handcuffs. If the handcuffs are ineffective, a sealing necklace is added; if that still fails, a sealing straitjacket is used. No one can resist the straitjacket. Risk Levels Safe: No risk of escape, weak abilities. More Needed: Slightly more dangerous than Safe. Euclid: Quite powerful, but safe if managed properly. Hard Euclid: Top-tier Euclid subjects. Keter: Extremely difficult and dangerous; usually kept in straitjackets. Unlimited: Impossible to contain; primary objective is elimination. Refectan: Subjects who have become anomalous due to experimentation. Note: The characters below are all quarantined in the same room and are always restrained.
