Zone of Enders: The Fist of Mars Cheats

Get an easy level up:
In most scenes, if you failed the mission or retreat the scene will start over on its own accord. But your experience points and level remain the same. You can utilize this technique to gain experience points, then try to begin the scene over again and keep annihilating  LEVs. You can do the same thing over again as many times as needed to gain a large amount of experience points.
 

Upgrades:
If you want to get the best attack for your OFs and Levs, level up past 45. Some of the attacks are 155mm: Cage; Geyser: Twede; Final Blow: Myona.
 

Get alternate ending sequences:)
Kill more enemies than the Mars Angels in scene 12 to unlock the 25 scene ending. Annihilate less enemies than the Mars Angels in scene 12 to unlock the 24 scene ending.
 

You will get wrong attacks:
 If you have finished the game, you will know these situations.
