The game starts when you are Cloud a Shinra inc soldier and you quit and join a team of mercenaries called avalanche. They want to destroy all of shinra and make midgar a free town. You will fight in over 1000 battles with monsters and Hard bosses. You will have a long journey to finally reach your goal... To KILL Seperoth for all people. He was a friend of yours until he went crazy and started killing. His artificial mother or not real mother Jenova is someone you must kill. She is deadly and youll find out how to kill her later in the game. Seprioth is the enemy, you won't find that out until later in the game. I don't want to spoil the game but.. its the best game ever made.!
