Hey fellow Final Fantasy VII fan! When it comes to mission walkthroughs, preparation is key. Make sure to stock up on healing items, equipment, and materia before heading into battle. For Shinra Headquarters, utilize Barret’s long-range attacks to take out enemies from a distance. In the Train Graveyard, be cautious of the Ghost enemies and use fire-based magic to defeat them quickly. When facing the Turks in Sector 7, focus on taking out Reno first to make the battle easier. Remember to always assess the enemy’s weaknesses and adjust your materia accordingly for a successful mission! Good luck!
