Note that they are always available in the remastered version of the game, and the original version had a cheat that allowed using alternate outfits during the initial playthrough. This affects Gadgets, WayneTech upgrades and Riddler Trophies/Enigma Datapacks. This means that any gadgets collected on the first playthrough are instantly usable on New Game Plus.
Enemy layouts are changed, meaning that early-game enemy encounters might have end-game enemies/weapons on them.
