Arknights is a tower defense RPG with gacha mechanics. To succeed, you’ll need to make your heroes, called Operators, as strong as possible. Arguably the biggest upgrades are special items called carrier modules. They do improve character stats, but with the caveat that modules are created for specific Operators and cannot be used by anyone else. Take a look at our Arknights module tier list to make the right decision.
