The Quest for the Best Editor
Alex discovered that while traditional "save editors" for the Switch are rare, there are powerful tools and methods the community uses to customize their experience:
OpenHeroSelect (OHS): This is considered the "gold standard" for those looking to heavily mod the game. While it has a steeper learning curve, it allows players to build a custom hero stat file, add new characters, and modify rosters with significantly fewer errors than other methods.
0% Save Files with All Unlocks: For players who want to "start fresh" but with everything available, the community often shares save files that have all characters, costumes, and S.H.I.E.L.D. depot items unlocked from the start.

XP ISO-8 Farming: Equipping white "Team XP" ISO-8 crystals can boost leveling by up to 400%.
The Shield Depot Trick: You can buy unlimited Enhanced XP Cubes from the Shield Depot once you've farmed enough credits in rifts like Lambda 48 or Omega 61.
