M.A.S.S. Builder, developed by Vermillion Digital, is an action RPG where players pilot a customizable M.A.S.S. (Mechanical Assault Skeleton Suit) to combat the alien threat of Quarks. Set in a post-apocalyptic world reshaped by war, the game’s standout feature is its comprehensive customization system, allowing players to design their mechanical suits for both aesthetics and playstyle without compromising performance.

M.A.S.S. Customization System

The game offers an intricate system for building your M.A.S.S., where all armor parts are purely aesthetic and don't affect stats. This allows players to design their suits with hundreds of interchangeable components, ensuring both functionality and visual appeal. Weapons are equally customizable, with options to modify their appearance and functionality, letting players adapt their loadouts to their combat preferences.

Combat Against the Quarks

Players will face hordes of alien creatures known as Quarks, including massive variants that actively hunt you down. The fast-paced combat emphasizes mobility, with boosters enabling swift movement across battlefields. This dynamic system ensures engaging encounters as you utilize your customized M.A.S.S. to outmaneuver and defeat enemies.

Post-Apocalyptic Worldbuilding

The game’s setting depicts a shattered Earth where humanity has retreated to shelters, developing advanced technologies like the M.A.S.S. to survive. The narrative includes detailed lore and environmental storytelling, enriching the backdrop for your battles against the Quarks.
