Hey fellow Final Fantasy VII player! When it comes to mission walkthroughs, preparation is key. Make sure to stock up on healing items and buffing materia before heading out. For the Train Graveyard mission, focus on using Lightning and Ice materia to exploit enemy weaknesses. In the Shinra Building infiltration, use Steal materia to snag important items from enemies. And don’t forget to level up your characters by engaging in as many random encounters as possible. Happy gaming!
