In Anime Last Stand, codes are special redeemable sequences that players can use to unlock rewards, such as in-game currency, characters, or boosts. These codes are typically shared by the game developers on social media platforms or within the game’s official community channels. Players need to enter the codes into the designated section of the game to claim their rewards. These codes are usually time-limited, so it's important to redeem them as soon as possible to avoid expiration. Always keep an eye out for new codes during updates or special events.
