STALKER is a Finnish science fiction roleplaying game based on the novel of Russian writers Arkadi and Boris Strugatsky. Event called the Visitation, perhaps by alien visitors to Earth, has left behind six locations thrown in to chaos. In these prohibited zones, or simply "Zones", laws of nature have turned against themself and all life has either been destroyed or hideously distorted. Stalkers are adventurers and criminals living outside the society who are looking the remnants and technology of the alien civilization. Everybody needs them, even those who are responsible for guarding the Zones, because stalkers have gone farther in the zones than anyone else.
In May 2011, Burger Games announced that the Stalker RPG was going to be made available in the English language with a likely release date of July 2011. Due to budget restraints the progress on the project was greatly slowed and the English PDF was released on March 11, 2012.
