Weapon customizations can be found throughout the game or bought from the merchant. In addition to fully upgrading each weapon, players will need to customize weapons to their max. Not all upgrades are available from the start of the game but progressing through the story will eventually make all purchases available to players. At the weapon upgrade shop, players can spend Lei for boosts to their weapons stats- specifically damage output, rate of fire, reload speed, and size of magazine.
