"SFZ Project: Episode Zero. Deluxe Remake" is a complete reimagining of the 2020 mod with updated gameplay and visuals, as well as redesigned Kordon location and various side-quests. The general plot of the story remains the same - in the Zone there was a third large release, which attracted the attention of Professor Sakharov, who supplied a group of scientists to go to the Chernobyl NPP. The connection with the expedition is cut off and a former mercenary and friend of the professor is sent to the Zone to find out the circumstances.
