I don't have a manual for this game. Can anyone tell me what each stats do to the mech? I'm confused about power, strength, and piloting. Does piloting make it control better? Strength and power seemed similar.

No one?

******************************************************************************
4.Stat Information
******************************************************************************

This Section explains each of the stats that your character's possess.

Power

Power is a little misleading name. Power should probably be called "Payload".
Anyway, power determines how many missiles that your Valkrie can hold. Higher
power equals more missiles. More missiles equals more mayhem. This is good.

Importance: As said before, more missiles are good to have, so power is a good
stat to build. However, other things are more important, so unless the
character that your using has very low power, I wouldn't put it very high on
the priority list.

Stamina

Stamina is pretty self-explanatory. The more stamina you have, the more hits
you can take. That being said, understand that Stamina equals LIFE.

Importance: Like it or not, you ARE going to be hit in this game, period.
The more life that you have, the better your chances of surviving. There's no
armor in this game either, making life all the more important.

Strength

Strength determines how much power that both your Gunpod and Missiles have.
More strength equals stronger shots. Uh, there's not much more that can be
said about it.

Importance: #1. The stronger that you are, the quicker that the enemy dies,
the quicker the enemy dies, the less you get hit, the less you get hit, the
longer you stay alive. That, and the more enemies you kill, the more
experience you get to buy more upgrades. Besides, the object of the game is to
kill the enemy.

Piloting

Piloting affects the speed of the Valkrie in Fighter and Guardian modes. When
I say speed, I'm referring to all aspects of speed, including up and down
movement

Importance: Having extremely low piloting is a bad thing that will hinder your
performance and cause you to take damage that could be avoided. That being
said, after a certain amount, really high piloting becomes superfluous.

Speed

Speed increases the movement speed of the Valkrie in Battloid mode. That's it.
Speed does nothing for the other two modes.

Importance: Nonexistent. The only reason to go Battloid is when you want to
go slow or aim. There's no need to increase the speed of standing still.

Google is your friend dude.

Thanks. I looked it up and got gamefaqs too, but it was in spanish and when i translated it seemed there were things missing. It wasn't near as much as this. Translator wasn't working right maybe?
