Overview Together with meteorites, the Earth received alien life spores which started quickly developing under the planet's conditions. People now faced a highly aggressive form of life capable to parasitize humans, totally overriding them. Within several days after the catastrophe, aliens spread across vast territories and captured many objectives. The game consists of a military campaign to resist the invasion and the main character's participation in it. In the course of the game the player will have to carry out a number of tense and hazardous missions on the objectives captured by aliens, saving human survivors, creating diversions, preventing nuclear weapons launches, getting important information, samples and much more. There are 13 enormous levels. It's possible to perform operations in both the daytime as well as night, this is left for the player to choose.
