Sisters (Сестры) is a russian survival mod for Gothic II:NK. The main character is a young girl searching for her missing sister in the hostile environment of an unfamiliar land. The game consists of four chapters and is considered very difficult in Russia. The heroine experiences hunger and thirst, expressed by additional bars on the screen and resulting in death after a certain amount of time. From the beginning, she must learn basic skills like cooking and acquire the simplest items and tools to be able to perform practically any task. The number of items carried in the inventory depends on their weight and the heroine's strength at a given stage of the game. A timer is introduced to show the elapsed time in the game, necessary to maintain vital functions and complete certain tasks and activities. The heroine can use a sword that deals magical damage, use runes that can be upgraded, and also learn alchemy, which is much more advanced than in the base game, as she can create her own potions with specific effects.
The mod's plot is unrelated to the Gothic game, but is based on the game's modernized worlds. The main character is a young, fragile, and modern girl, thrown by fate into a pristine world, where she will spend three chapters searching for her missing sister.
