The '92 arcade version of space invaders, was originally named Space Invaders: Reborn and was all over the world in every single arcade. Unlike the classical 80's version, the aliens descend, there are walls to hide behind, there is much more animation to the characters and there is a bit more details in the shots. It also has a hi-score system and multiple levels. Although this version does not yet have have power ups, that will come soon in Space Invaders: Millenium. Have a nice day. =D
