Armored Ridden are a Common Ridden Variation in Back 4 Blood alongside the Charred Ridden, Blighted Ridden and Volatile Ridden and are the most toughest of the 3 due to the Riot Armor they wear.
The helmet can be knocked off of Armored Ridden to allow for headshots. This has a chance of generating Makeshift Armor when using Sunder or if Sharice is on the team.
