Description
Mount Nibel consists of a dangerous, winding path that leads to the summit, where a Mako Reactor is located.
You should already be familiar with its layout as you visited here during Cloud's story.
Objective
Your goal is to reach the summit and defeat the boss, allowing you to pass it and continue with the game.
When you reach the summit you will see a layout of ladders and pipes. Climb to the bottom first, this will make sure all the ladders are extended down. Then climb back up and walk into each pipe in turn until you have picked up all the items.
Now walk up to the save point and save your game, however do not walk up to the Boss just yet, instead take the other path out of that area. This will allow you to explore some more caves (that you visited during Cloud's story), where you can pick up more valueable Weapons, items etc.
If you follow the caves all the way through, you should find yourself back where you started, use the save point again, making sure you party has maximum HP and MP, then go up against the boss.
Once he is defeated follow the path he leaves open, and you should be returned to the World Map, where you should now head for Rocket Town.
Bosses
The Boss you have to defeat in order to pass is called the Materia Keeper. He has an Enemy Skill, Trine, that your can learn from him, that you cannot learn at any other point in the game, so make sure one of your party has the Enemy Skill Materia in their Weapon or Armour.
