The year is 1984. Researchers at the secretive Bentan Labs are celebrating the completion of their latest secret weapon project: a previously unknown type of mildew, capable of spreading and consuming any kind of vegetation, which makes it ideal for attacking stockpiles of enemy food. When a corporate sponsor is accidentally infected, the mildew's spores are set loose across the facility. As aggressive soldiers flood the complex and the infected staff begins to mutate, the survivors come to realize that the mildew is, in fact, an alien creature! To avoid agonizing deaths, the remaining scientists must join forces with Toxic - a mysterious mercenary who has infiltrated the building on a covert mission. Can anyone escape the clutches of the out-of-control fungus and the army of crazed mutants it has created? Alien mutations, dissolving flesh, action, and gore await you if you dare!
