Good old SI with some needed twists. IMO this plays and looks a bit better than Space Battle. Though remembering and recognizing the many options is pretty tough.
Good graphics (I just don't like the flashing background), sound and controls. (thrust26)

Nice game with a lot of power ups! (pieffe)

I don't like Space Invaders normaly, but this colorful version is pretty cool. (newcoleco)

A decent version of Space Invaders, but a couple of marks have to go on account of the graphical flicker and the lack of shields. (Matt_B)

A nice Space Invaders clone with colorful enemies and some new items to collect. Cool. (2600fan)

Nice game. (ChrisRead)

Cool twist on an Classic Game. Space Arkanoids. Power-ups really make this fun to play. (DaveNeuman)
