Mono description

Mono

Mono is a 2D action game set in a stark monochrome world. You play as an autonomous combat AI deployed into this realm, supported by a companion AI. Together you must battle a growing threat and push toward the enemy stronghold to restore peace.

Core Experience

Explore a network of interconnected areas, uncover hidden items, and confront formidable foes. Progress hinges on learning from encounters and expanding your toolkit to reach new regions and challenges.

Combat

Engage with a blend of melee and ranged attacks, complemented by dashes and slides to control spacing. There are no invincibility frames—dodging is not an option—so victory comes from methodical hit-and-run tactics, precise positioning, and reading enemy states.

Damage scales with the enemy’s state, encouraging experimentation with timing to discover the optimum moments to strike.

Progression & Exploration

Items gathered through exploration and combat unlock nodes in a skill tree, empowering you to boost stats and gain new abilities. Finding new actions expands your exploration possibilities, and revisiting earlier areas can reveal fresh discoveries.

World & Story

The world is designed to be explored freely, with multiple interconnected zones that reward curiosity. Interact with characters scattered across the world to learn more about the story’s background and the anomaly threatening the realm.

Mono emphasizes strategic movement, adaptive combat, and a sense of discovery as you work with your support AI to restore balance to a monochrome world.
