Talking about the methods of upgrading, the upgrade mentioned here is not the traditional level-up in games; it's not about character leveling. The upgrade here actually refers to unlocking weapons, by which usage levels are increased, thus obtaining the right to use more weapons. This is what upgrading means in the game.

To complete the weapon upgrade, what you need to do is finish the levels and get high scores. After obtaining such scores, you can unlock the weapons. This is the way to level up. However, when upgrading, please note that the weapons in the game are bound to specific roles.

In simple terms, some weapons are bound to certain jobs, and only those jobs can use this series of weapons. This means that when you're upgrading and unlocking, you need to first check which job the weapon is bound to, and then use that job to play.

This way, you can upgrade the corresponding series of weapons and use them. This means that the game levels are separate, with different jobs corresponding to different levels. To unlock everything, you need to play all the jobs, which is how you truly reach the maximum level.
