Hey there! When it comes to mission walkthroughs in Final Fantasy VII, preparation is key. Make sure to stock up on potions, ethers, and status-healing items before heading into any mission. Always assess the enemy’s weaknesses and strengths to plan your attacks accordingly.

For example, in the Sector 7 Slums mission, focus on taking out the enemy guards first to prevent them from calling for reinforcements. Utilize Cloud’s Braver or Barret’s Big Shot limit breaks to deal significant damage to tougher enemies.

Don’t forget to explore the area thoroughly to find hidden items and materia that can give you an edge in battles. And always remember to save your game frequently to avoid losing progress in case things don’t go as planned.

Good luck on your missions, and may the power of materia be with you!
