Gregory is a type of zombie that appears in House of the Dead 2. He appears as a balding man with putrid, gray-green skin. He is adorned in bloodied chainmail like a medieval knight with a sun-shaped crest adorning his chest. He carries a large Claymore sword that is streaked with blood.
Appearing in the fourth chapter of the game, Gregory advances on the player while holding up its large sword which shields it from the player's shots. It will attack by raising the Claymore and then bringing it down on the player in a heavy slash. Gregory is most vulnerable when raising its sword as its head is briefly exposed when attacking. Shooting its arms to make it drop the sword does not work.
