Trivia
The Knight Armor is based on another one of Capcom's games "Ghosts and Goblins" where the protagonist Sir Arthur has similar looking armor that breaks apart after one hit causing him to continue the fight in his loincloth "underwear".

Thankfully the Dead Rising 2 version isn't nearly as fragile, though when the armor finally does break, Chuck is similarly left in his underwear taking normal damage.
