Space Invaders 91 1991 By: Taito

Overview:

The classic arcade hit, remade for the... 90's. Still a very simple idea, but this edition features animated sprites rather than just moving back and forth. The background music is modern and fast, designed to make the game feel even more exiting than it actually is.
The biggest change with this version is that the UFO drops power-ups instead of just being worth extra points. Unfortunately, there seems to be no two-player mode, so although the High Score is still the Holy Grail of arcade games, you can't compete directly with your friends.
