This game is fun for awhile but it isn't very good. The graphics are great but that's about it. You play through the missions controlling a defender ship to defend your home planet. They can be fun for awhile. But after you get to the third or forth mission you will realize that in every mission your objective is to defend a building, defend allied units, or to rescue the colonists or a combination of two or more of those objectives. In many of the levels you have to fly around picking up colonists and dropping them off at your base while killing enemies at the same time. There is multiplayer but it is horrible. You can kill each other or do a co op mission. There is no targeting system so you have to aim right at your enemies to kill them. The control for this game is bad and very confusing. You press B to change weapons and it is very hard to tell how much ammo you have left. The most confusing part is how you move. You press R to move forward but if you press it all the way down you "strafe" left or right. You press L to go in reverse but if you press it all the way down you will drop all of the colonists you are carrying. The sound isn't that good, but it isn't horrible. All in all, this game isn't even worth renting.
