One of the best Space Adventure games out there. Not only is it fast it also has strategy elements with each enemy ship dangerous and diffrent. The playfield (Space) has SpaceWarrior, Solar Energy ( helps you double your speed but reduces your score) and Enemy Crafts which are attacking Earth.Objective of the game is to save Earth from the Space Invaders by shooting them down within the time limit (Max.120 seconds for each Level) but without missing to destroy the Master Invader Craft. Space Warrior can score as many points as possible by shooting as many enemy crafts as possible. Destroying different space invaders have different scores. Mother Alien Ship (Level 4) has the highest score ( be careful they clone into 2 enemy ships when you shoot them), then Spacecrafts (Level 3), Battle Ship (Level 2), Master Craft (All Levels) and Flying Saucers (Level 1) in that order. In Level 2,if you miss to shoot the Battleship twice, then it will side shoot you. In Level 3,if you miss to shoot the Spacecraft once, then it will side shoot you. Each game session has 4 levels - If you score more than 2000 points, then you will be declared as GRAND-DEFENDER. We challange you to get to clear Level 4..;-).
