Arcade Video game published 46 years ago:

Invinco (c) 1979 Sega.

Another game in spired by "Space Invaders", this one includes some innovation on the aliens : One row blinks in and out of view, another row's aliens roll so as to make themselves harder or easier to hit, and a 3rd row of aliens each take (at least) 3 hits to kill. A 4th row has aliens that turn into bombs, blowing up everything around them to make your job somewhat easier.

- TIPS AND TRICKS -

Time your shots when aiming at certain targets. The white aliens turn invisible on you, so try to hit them when they're visible on the screen. Also, there's a period of time that the top aliens are invulnerable to your shots while they change to another form; wait a second or so before shooting them again so you don't waste shots and time.
