A group of stalkers, for the first time, reaches the very heart of the Zone-the Chernobyl Nuclear Power Plant-and triggers a cataclysm on the brink of a catastrophe. An immense blast of anomalous energy transforms the Zone: the once reliable and relatively safe roads are no longer so, the landscape is wiped clean by outbursts of anomalies, and previously unknown areas appear on the Zone map. Stalkers and expeditions perish or end up isolated within the lost territories.
I don't understand why this episode is so underrated. The start is very interesting and it changes how we feel STALKER. The Faction War was also a really good challenge (when it wasn't not buggy)
Anyway, I was kinda disappointed when you cannot go back after going to Limansk and the end could be much better.
