A game Mary Skelter: Nightmares – about the adventures of two prisoners in huge catacombs named Jack and Alice. One fine day, Mary Skelter frees Alice, but she refuses to leave without taking Jack with her. Their escape should lead to the City of Liberation, where former prisoners like them lived, but until then they will need to go to the surface of the earth, having first carefully explored every corner of the underground prison. During the passage, friends look for cores, objects that cause mutation of the environment when destroyed, and other useful artifacts. Alice, Jack and Mary join the team with other fairy tale characters including Sleeping Beauty, Cinderella, Rapunzel, Thumbelina and many more.

During the passage of Mary Skelter: Nightmares, the heroine will have to go deep underground to fully explore the dungeons. During the process, you will encounter many enemies that you will need to fight in turn-based battles. Moreover, each character participating in battles has their own unique abilities. For example, Jack cannot directly attack or defend himself, but is able to use various artifacts, take a blow on himself instead of one of the group members, or splash his blood on someone in the team to restore his life. You can complete the game on any difficulty. Depending on the selected mode, the number of enemies and their abilities vary. The main thing is to stay alive, protect your friends and defeat all the enemies you meet along the way.
