[Guyver]

Ok from the first part I concluded that it was basic ammunition.

The second part I guess is the nodes for armor slots.

The third, I would be oblivious to. Like I don't know how to open a door?

The rest is self explanatory. Although I am slightly disappointed by the train system. But the more I think about it, the more it seems to fit. It helps add a retro type style to a futuristic world torn by war. Then again, that was the Sapien city. The alternatives may have something different. Let's just pray it isn't like the zeppelins in WoW.
