M.A.S.S. Builder throws you into a dark near-future where humanity’s golden age was cut short by the sudden arrival of monstrous void creatures called Quarks. As commander of a private military company, you pilot massive Mechanical Assault Skeleton Suits (M.A.S.S.) to fight back, customize your machines, and carve out a future for what's left of humanity. The game mixes fast-paced action-RPG combat with a very deep visual and functional customization system, putting you in control of both battlefield tactics and design aesthetics.
