After nuclear war, the Earth becomes inhospitable to human life and is soon populated by aliens. The human survivors retreat underground and in desperation construct an android, the Cybourg 64, to exterminate the aliens. But as each generation is destroyed, a new, brighter, more deadly strain evolves.
The Cybourg starts with six lives and an arsenal of ten mines, which he can lay around the devastated landscape; bombs, TNT and lasers are added later. Some aliens are invulnerable to particular weapons, but destroying others of course earns you points.
The letters E, X, T, R, and A appear among the constructions on the earth's surface, and can be picked up to build the word EXTRA for bonus points. But aliens can destroy the letters...
Strings of transparent bubbles give the Cybourg protection against alien attack and can be used to pen in clusters of alien eggs (harmless till hatched).
Alien Evolution is an appealing game with pretty graphics; but visual appeal isn't everything. It's very well presented, and the gameplay is all there, but I got bored quite soon. Despite its high quality appearance, I see Alien Evolution as just a jazzed-up puzzle-cum-arcade game.
I thought I'd loaded Ant Attack (an ancient pre-Crash game) by mistake! Alien Evolution is graphically very similar to the likes of Ant Attack and Zombie Zombie, featuring high-class isometric graphics still good by today's standards, though the scrolling and animation aren't up to much. But Alien Evolution is also enjoyable in its own right. Playable virtually from the start, it has some nice touches - like heaving bubbles around to trap nestles. And though it pets a bit repetitive, there's enough action to keep you amused.
Sprites and backgrounds move smoothly in Alien Evolution, and the aliens fairly whizz round the screen. And there's a nice tune playing on the intro screen. This game is obviously derived from Ant Attack, but that's no drawback and it's fun to play - for a while. A good buy for fans of fast-moving 3D games.
