Another example of how to turn a potentially interesting concept into a mediocre game.
Marred by simplistic graphics and jerky scrolling, Alien Evolution puts you against an alien invasion which you have to fend off with more subtle means rather than just zapping them. Unfortunately gameplay turns soon into a series of chores, like lying strings of mines in order to block the proliferation of enemies. Other weapons become available as you progress in the game, but by then you'll probably be already overwhelmed by boredom.
