Game process Void: Dementia takes place dynamically, offering a hardcore level of passing and many ways to achieve the goal. In the action adventure, locations and obstacles are generated procedurally, each time making the passage a new one. The main character finds herself in a strange environment, where she will gradually restore her memories. Each action she takes allows her to return fragments from her past life.

The user controls a militant woman who will have to fight various opponents, finding herself on a new life path. During battles and overcoming traps, she restores parts of her memory. She is trying to achieve a full return of her memories, but for this she must go through a difficult and bloody road. On the journey, you will meet many bosses with their own sets of moves, strengths and weaknesses.

The protagonist is a master of weapons, freely using three types of melee weapons, such as a katana, dual blades and a two-handed sword. The chosen weapon affects the attack speed, combinations, special abilities and animations. The gamer can try out the entire arsenal and choose the most liked weapons that suit the style of passage. In the story mode, you will face 5 bosses, with a total of 50+ destructive abilities.
