Gorky 17 is a combination of adventure, RPG, and strategy elements. NATO intelligence services report that, for reasons unknown, the Russian military has destroyed GORKY 17, one of the old Soviet "Secret Cities". A year later NATO takes over a former Russian secret base built on Polish soil. Diggers discover a laboratory complex in the completely demolished town. After examining the wreckage, NATO decides to leave the lab as it is. But shortly afterwards the town's previously deserted streets are suddenly teeming with hordes of grotesquely deformed creatures. Word soon gets out to the media, making it impossible for NATO to simply destroy the site. So troops are ordered to hermetically seal the area. Nobody is allowed in or out. A team of three NATO specialists under the leadership of the Canadian Cole Sullivan is sent in to examine the horrifying events on the ground.
