Terraformars

With Earth quickly becoming uninhabitable due to a swelling population, humans develop a project to terraform Mars, one that involves leaving cockroaches on the planet's surface. Five hundred years later, Earth sends a team of astronauts to "exterminate" the roaches and prepare Mars for colonization. Once there, however, the astronauts discover that the roaches have rapidly mutated into terrible humanoids, more powerful than any normal human. But the astronauts have been given special, insect-like abilities to deal with the roaches, and a violent struggle for control of the planet ensues.
