This game could have honestly been a good game. It starts off fun to play until you figure out that the battle system is broken. The game plays as a turn-based grid strategy rpg but you have 2 modes of combat: 1 is impossible to win and another is impossible to lose once you realize that you can always dodge by always moving in an ellipse during the allotted time. Fortunately, the story is pretty good. You play as a stowaway called Cage, who eventually joins a group to fight terrorists using giant robots. The dialogue is very interesting between characters but it has one flaw; it is too long. Like the Super Robot Wars Original Generation games, expect to read for 10-15 minutes before going to the next chapter or battle. I am just glad that the dialogue at least remains more interesting although it really needed a save feature in the story sections because it is on a portable system, the Game Boy Advance. At least the game had a good presentation, with a nice soundtrack and graphics.
Combat is done in two ways. You can skip battle animations, but this will slow your dodge to a cripple, in which you can get killed in about 1-2 hits in the later levels (with a low percentage of hitting/dodging). You can also play with the battle animations, in which when you attack, you have to find an enemy in first person and shoot him. This is pretty easy to do and you'll have much higher accuracy than if you skip the battle animations. As I said before, you'll never get hit if you move in an ellipse when it is the enemy's turn to attack. This turns Zone of the Enders: The Fist of Mars into a dichotomy of 2 broken difficulties because you will either win or lose too easily based on the battle system you use. At least, the combat system was unique although it is flawed and it had a good story.
