Invinco

Invinco (インビンコ) is a Space Invaders clone released by Sega in 1979 for VIC Dual hardware.

Though it is essentially the same game as Taito's, the aliens don't just move left and right - one row blinks in and out of view, one row rolls about making it difficult to hit and another has aliens that turn into exploding bombs when hit, taking out everything around them.
