Malevolent Madness invites players into a tension-filled horror adventure, offering an experience rich in mystery and puzzles. A mysterious time machine unleashes extraordinary powers that could disrupt the balance between universes, but this discovery becomes a significant threat to humanity in the wrong hands.

Players guide a scientist with special abilities assigned to secret projects. Hidden in a dark cave, a time machine, which can only be activated by a specific DNA, initially shows no response but suddenly starts to function unexpectedly. This machine poses a risk of annihilating the universes if the same matter exists in both. As our character uncovers the terrifying secrets behind the machine, they decide to quit their job, yet a malevolent professor wishes to use the machine for his own purposes and abducts the character, subjecting them to torturous tests. The horrifying events grow increasingly complex.
