Hey fellow Final Fantasy VII fan! When it comes to mission walkthroughs, preparation is key. Make sure to stock up on healing items and have a good balance of offensive and defensive materia equipped. For missions like the Sector 7 plate retrieval, focus on taking out enemies efficiently to conserve your resources. Don’t forget to explore every corner for hidden treasures and shortcuts. And always keep an eye on your party’s HP and MP to avoid any surprises during boss battles. Good luck out there!
