Hey there, fellow Final Fantasy VII player! When it comes to mission walkthroughs, preparation is key. Make sure to level up your characters and equip them with the right materia before heading into any mission.

For example, in the Sector 7 Slums mission, focus on using Lightning materia against the Shock Troopers for their weakness. And don’t forget to steal from the Security Officers for some extra items.

In the Train Graveyard mission, be sure to equip your characters with Fire materia to deal with the Ghost enemies effectively. And keep an eye out for hidden paths that may lead to valuable items or shortcuts.

Lastly, in the Shinra Building mission, make use of your best offensive materia like Ice and Fire to take down the tougher enemies. And remember to conserve your MP by using physical attacks when you can.

Overall, pay attention to enemy weaknesses, utilize your materia wisely, and always be prepared for anything that comes your way during missions. Good luck, and may your battles be victorious
