The world of the Witcher game is based on a dark fantasy universe. The main character is the famous monster hunter, known as the "Witcher." In this universe, there is no division between good and evil, but only on the actions and their consequences. The world is full of monsters, evil creatures, and other dangerous enemies. The main task of the player is to survive in this world and eliminate all the monsters.

In order to survive, the player must develop his or her own skills and fight enemies. In addition, the player can find help in the form of companions and allies.

Atmospheric Nights is a mod that changes the atmosphere of the night. With this, visual effects look much better and brighter and nights will be dark but not pitch black.
