Hello you, yes you, sitting there in front of your computer/laptop. I see you have come for my guidance or perhaps you are just bored, if its the latter please click the following link: http://www.youtube.com/watch?v=pYV9IOJ8RRc . That link hopefully took you to GrandPyromania's Lets Play of the first game. It's certainly more entertaining then a bunch of text, and if you happen to be in a need to a Kingdom Hearts 1 walktrough look no further!
Anyway, ON TO OLYMPUS!
Olympus Coliseum
An errand to run
Popping in we appear in the Underworld, the stairs are right there with holy like light shining, but a scream is heard and Sora finding his chance to maybe get lucky for once, well we are gonna save her, weirdly this is the only time when you are in control with a battle music going on. Anyway go ahead and "Help her up", the girl as you saw introduces herself as Megara and acts like a total hot bitch. She talk about some "Wonderboy" and wanting to speak to Hades the lord of the Underworld blablabla. She sends us out to go and talk to Hades who is a a good 20 minutes away.
Save Up! go to the Abilities menu, if you have been using Valor form enough you should have the ability Auto Valor which gives you a quick option to press and RC to go to Valor Form in an instant when low on health, it will give you all your HP back and of course its Valor Form so you're guaranteed to be able to destroy anything and everything that crosses your path, but you may have noticed that your Drive Gauge is grey and is chained, meaning you cant use drive forms, but don't worry we will fix that in a jiffy. . Another would be Aerial Sweep, a powerful aerial finisher. Goofy also has obtained Goofy Turbo so equip that too.
Next go to the Synthesize store, they have some new weapons for Donald and Goofy, the Comet Staff and Falling Star they cost 200 munny each and you should have more then enough, remember to hand over all your materials while your at it.
Waiting for future developments...
