As one of the first and most popular videogames of all time, Space Invaders is also one of the most copied. Atomers is a slick shooter that merges elements of Space Invaders with Galaga-style enemies. The story is a pretty standard one - save the planets by blasting aliens. But the main thing is that this is a simplistic game that will have you gripped for hours.
Like Space Invaders, you sit at the bottom of the screen as the alien ships shoot and swoop down on your from above. One of the cool things about Atomaders is that every time you shoot an enemy you'll get a different charging weapon type. Once you've collected four of these, you can reel off one shot to devastating effect. This, and the addition of mother ships and end-level bosses adds a little more interest to the standard Space Invaders gameplay.
Graphically, the game is very impressive, with gorgeous backgrounds, smooth animation and some rad explosion effects. With a kicking soundtrack and some great FX, this is a highly polished creation, compared with early Space Invaders games.
