Mutant Storm Empire, like it's predecessor Reloaded, is a classic dual analog top down shooter with not so classic graphics. In fact Empire's graphics are gorgeous, with bright colorful areas and enemies abound. The enemies themselves, called "beasties" in the game, range from the typical mechanical robots, etc., to the more "organic" kinds, such as a beastie that seems to blow its nose at you, and a giant blue fish which you kill by shooting at its giant blue (the color) balls. And while on the surface things seem fairly simple, there's a pretty in depth combo system that allows you to work with your teammate to maximize score. Which, of course, is what this type of game is all about.
To gain maximum score, you need to maximize your multiplier. How do you do that? By beastie combos. Beastie combos are obtained by shooting only bad guys of a certain type. One you shoot enough in a row, your combo bar grows by a small amount. For instance, shoot 10 green robots and your multiplier bar will slowly grow. Then shoot 10 purple ones for another combo bar increase. This is where the teamwork comes in, as you must communicate with your partner as to what enemies you are going to go for.
The co-op aspect of the game is pretty straightforward, with each player controlling an amoeba style little creature to shoot baddies. There's no special story or special modes for co-op; you'll play through the same four worlds with or without your buddy. If the game has a downside, it's that it can be pretty difficult, and it can be frustrating trying to get through certain parts. Thankfully you are allowed to continue or start the game at any section or world you've already completed in single or multiplayer (Of course, to maximize your score you'll want to start at the very beginning).
All in all if you like games like Smash TV or Geometry Wars you are going to like Mutant Storm Empire. The really nice thing is, the game can be as simple or as complex as you want.
