Gotham Knights trophies have been published well ahead of the game’s October 21 release, and there’s some good news for those who don’t want to play on the highest difficulty: there are no difficulty-based trophies. However, there’s a good mix of combat trophies, collectible hunting, and side quests. One trophy does require completing all Batcycle time trials, but if this list is anything like Marvel’s Spider-Man or Horizon Forbidden West, the time trials should be fairly easy on lower difficulties.
