Evolva, a tactical shoot-em-up for the PC, immerses the player in a visually stunning 3-D world, offering a rich game-playing experience. Driven by Computer Artworks' A-Life technology, this world and its alien inhabitants form a challenging environment. The player must fight against an alien parasite that has infected a planet. This parasite has an army of guardians to protect it, and they will have to be stopped if the player is to ultimately stop the parasite itself. The player takes control of a team of customizable creatures called Genohunters and guides them through a unique gaming world, mixing the excitement of a fast-paced shoot-em-up with the tactical elements of a strategy game.
