In Metal Slug 7, the global community is attacked by a force beyond our comprehension. We must face down the assailants and build a future without them. The story progresses normally, with some new and unique features. When playing as a character that we've built up over time, for example, our character's stats will increase by a certain amount. However, this increase is only good for a certain amount, and if it's not earned through playing the game as usual, the character's stats will decrease the entire game. This is the power of the game's power-ups! In order to get as many as possible, we need to use as many of these things as possible.
