R-Naught is an action game with horror elements and a bizarre turn-based combat system. The player will have to fight with huge mutated animals and nature, which has decided that it is now in charge, and humanity has no place here. The user will have to explore locations, communicate with intelligent beings and fulfill their requests in exchange for information.

Several years have passed since the beginning of the pandemic and in this world people are still forced to be isolated, continuing to sit in their apartments. Nature is beginning to increasingly take over the liberated territories, and wild animals are beginning to settle in areas where people used to actively walk. Corporations at one time did not miss such a great opportunity to make more money and profit from poor people as best they could. Against the backdrop of all these events, the protagonist’s sister mysteriously disappears. Disappearances have become common recently and many believe that the government is involved. In any case, the protagonist decides to leave the house and find a relative.

R-Naught has a classic character development system with increasing the character's level, as well as developing his combat skills. They can help him not only fight bosses more effectively, but also push the plot to another branch of development. Here, dialogue choices and all the actions of the protagonist matter and will affect the story and its ending in the future.
