Greg, decorated American military veteran, was tasked by the United States military to solve the alien epidemic because of his brave actions in the last World War on earth. He has been in a coma in a forgotten hospital trapped by a foreign non-terrestrial being for decades.
Greg awakes from his coma and realizes he's not the only one in the dark, lifeless, and forgotten building and that he must vanish the alien.
Find and use your weapon and/or radar and hide behind walls, under tables, and closed doors to escape the alien. Be careful when you explore the hospital as the alien can hear you walk when you least expect it.
