In this game, the whole world is your battlefield! Your mission is to defend it from the hordes of alien invaders. Your defense depends on how well you manage to assemble and fight the suit.

The game is set in the distant future. The Earth has been invaded by an alien race. The aliens have a goal to eliminate the humans. The only way to defend the Earth is to create a powerful super weapon. The super weapon is the only thing that can stop the aliens. You have to build it, craft it, upgrade it, and use it. You will face many challenges on your way. But the biggest challenge is the boss battle. You have to defeat the boss and prove yourself to be the greatest hero.

You can buy new parts to upgrade the suit. But you have to be careful. The upgraded parts will be more powerful. But the more powerful the suit is, the more likely you are to be defeated in the battle.
