Second Variety

Second Variety is a science fiction novelette by American writer Philip K. Dick, first published in Space Science Fiction magazine in May 1953. Set in a world devastated by a war between the Soviet Union and the United Nations, it follows the last remaining soldiers as they discover that self replicating robots originally built to assassinate Soviet agents have become sentient and are now plotting against both sides. It is one of several Dick stories examining the aftermath of nuclear war, and it was adapted into the 1995 film Screamers, with the 1954 story Jon's World later written as its sequel.
