The Iron Maiden crossover in Dead by Daylight brought in a lot of great content, but there was one killer whose lack of content was a missed opportunity. Of course, the chance to collect cosmetics in Dead by Daylight is one of the draws of the game's many events. It's not surprising for fans of a Killer or Survivor to be disappointed when they go without something new. However, there was one omission from the Iron Maiden collection that would have been perfect for a cosmetic. It might be one of Dead by Daylight's biggest missed opportunities in that department.
