Mass

About

Mass is a co-op puzzle game where two players manipulate physical properties to solve environmental challenges. One controls gravity while the other adjusts density, creating interactions that let you reshape the world. Puzzles require timing and coordination as you balance forces to unlock paths or activate mechanisms. The game’s strength lies in its dual-control system which forces constant communication and creative thinking. Mass has a modest but loyal fanbase, with Steam reviews highlighting its clever use of physics mechanics. Since launch, it’s retained a steady player count, particularly among teams that enjoy low-stakes but tricky puzzles. The lack of traditional health systems or time limits makes it accessible but no less challenging. Its focus on pure problem-solving and seamless co-op play sets it apart from more chaotic multiplayer games.
