Space Invaders is yet another classic arcade game remake by Activision. The game stays close to its roots while adding many power-ups and enemies. Based on the alien technology recovered during the 1978 invasion, the new Tank has been created to repel a new wave of invaders.
You can play either one or two players against the Invaders, who march down the screen in orderly rows and columns, at one of three skill levels. You'll start at Pluto and work your way through the Solar System to Mars, then Venus, and finally Earth . There are four common aliens (red, green, blue, and yellow), plus seven more less common ones.
You receive special power-ups by shooting four of the same type of Invaders in a row. As in the original game, there are also Mother Ships that fly above the action, but in this version if you hit them you can pick up other useful power-ups like shields or double shots. Plus, after fighting off several waves on each planet, you'll face a unique boss.
