Alien World is another shoot em up with various levels that scroll horizontally while others scroll vertically, and with a rather weird storyline and graphics. The game was released only for the Commodore Amiga, Atari ST and C64 computers. It doesn't offer anything new to the genre, but gameplay is simple and straightforward.
In the time of legends the world was doomed into darkness. The wizard of evil rules and imprisons your mind in the body of a ferocious alien. An alien similar to the famous block-buster movie though!!! That was his first mistake because you own the soul of a warrior. And so begins your action-packed quest to defeat the wizard and regain your humanity. You set forth to rescue your love interest, a beautiful girl named Merdb. She is held by Feg inside the Cave Of Dreams. The storyline is quite odd for a pure shoot em up game! Collecting pods can enhance your firepower, increase the speed of your alien(!) and activate Smart Bombs. Opponents attack you as expected. What may come up as a surprise though, is how gravity affects you and forces you towards the hot lava. Alien World has all the ingredients of a common shoot and blast game.
The Amiga version features a few more colors (up to 32) than the ST version (up to 26), but in general terms the graphics are pretty much the same on both platforms (although both are somewhat mediocre and sometimes weird). Note that the Amiga version has different background graphics than the ST (but still poor in detail), while the foreground details are the same. Although scrolling is slow, still the game is fun to play for shoot-em-up maniacs. The soundtrack is far from thrilling musical experience, and not the sort of music you leave playing loud while taking a bath. The Amiga version offers the same introductory tune during gameplay (but no SFX) in contrast to the Atari ST version which offers only SFX during gameplay.
