"Space Warriors" is a great game which is probably not good for you if you are not good at mashing three buttons at once, or if you have proud friends. Explanation for first reason: people will crush you if you can't press three buttons at once. Explanation for second reason: your friends will hate you because you will always beat them, as long as you can press three buttons at once and they can't.
Controls: 9/10 A cinch, but you do have to remember that 2nd does not shoot with your ship and that the bottom player uses 4,6, and +, not 7,9, and /.
Gameplay: 8/10 Fast, easy, though there are a few problems. There are instances when you go too fast and if you press MODE before you shoot at all, the calculator will freeze, RAM clear, and you will have to re-install the game. It is also not compatible with MirageOS, but you can fix it with the IonFix program.
Graphics: 9/10 Simple, yet satisfactory.
Memory: 10/10 Only 2k!!!
Replayability: 9/10 If you have lots of friends, this game will stay on your calc for a long time. But if you do not, it will barely last five days before you delete it.
Overall: 9/10 A good, one-calc multiplayer game.
