The Iron Spider Armor is a suit players can unlock in the "Turf Wars" expansion for Marvel's Spider-Man. It is unlocked after completing Bring the Hammer Down, the final mission in the DLC's campaign. It does not possess an associated suit power.
The Iron Spider Armor is an armored Spider-Man suit bearing Iron Man's color scheme. It is mostly a metallic red, with the spider emblem, eye lenses, bracers, and boots being golden.
Uniquely, when the Iron Spider Suit's Iron Arms suit power is equipped to this suit, the Iron Arms are completely golden.
The armor is based on the Spider-Man suit introduced in the pages of Amazing Spider-Man #529, where it is built for Peter Parker by his friend and teammate Tony Stark. It is mostly known for its appearance in the "Civil War" crossover storyline.
