Our take on Knytt Underground

The large open world trades tightly directed progression for freedom to explore at an individual pace. Players must also manage a time-sensitive central objective while the game presents a quieter, quest-led structure rather than a combat-focused one.

What is Knytt Underground?

Knytt Underground is an open-world adventure set on a planet abandoned after a destructive war.

Its remaining inhabitants live in underground tunnels while investigating their origins and the meaning of life. Players control Mi, a mute sprite who gains new powers and undertakes quests. The main objective is to locate and ring six fate bells before a chain reaction destroys the planet. Exploration spans more than 1,800 rooms, with movement built around running, jumping, climbing, swinging, and bouncing. Mi can change between human and ball forms, and the game includes story-focused quests, environmental exploration at an unhurried pace, dynamic characters, and ambient audio. The setting includes Sprites, Fairies, and other life forms.
