Hint: Overweight override:
When you build your AC, you will notice that there is a weight limit on the
selected legs. To override this, just finish the game so the overall % under
system reads 100%. To do this, just complete every mission. Keep in mind that
while you can load any leg type with whatever you want after you get 100%,
your speed will decrease about 2 1/2 for every hundred pounds that you are
overweight.
Hint: Sword wave:
Draw your sword and press X (jump) just before the downslash. If done
correctly, you will fire the fabled "wave" that all of the higher ranked ACs
use. To fire the "blue wave of mass destruction", simply do this trick with
the Moonlight blade. It can do over 1000 AP worth of damage.
