Sleepwalker Experiments are the larger and more heavily armored counterparts to Sleepwalker Patients. They possess more resistance to damage due to their size and armor and, unlike sleepwalker patients, they do not wield weapons. Also unlike Sleepwalker Patients, Sleepwalker Experiments can revive themselves an indefinite number of times, requiring them to be decapitated in order to be killed.
Experiments attack by punching and knocking over their foes. The can also disarm them and inflicting damage directly to their health.
