R. Kasal

R. Kasal was a scientist who worked in Mars City. He can be found working on a console just outside the infirmary near Marine Command. At the same time, the player witnesses a crazed patient being sedated in the infirmary. Kasal, however, pays no attention to this incident, and if the player tries to talk to him, he will say he's busy and doesn't want to be disturbed.

Kasal was most likely killed or turned into a zombie when the demons invaded the base.
