Character Level

Before heading into the final assault, it's worth preparing and increasing your character's level. It's recommended to reach at least level 40, preferably 50. In the Arasaka tower, where the final battle occurs, there will be many strong enemies, and without a sufficient level, you might not even reach the elevators.

Tower Assault

It's important to remember that during the tower assault, you can't save your progress. If you die during the battle, you'll have to start from the very beginning. Therefore, be prepared for complex and lengthy battles.
