Our take on M.A.S.S. Builder
The extensive suit and weapon customization adds build decisions and visual variety, but it also places more of the experience around preparation and modification rather than combat alone.
What is M.A.S.S. Builder?
M.
A. S. S. Builder is an action RPG about piloting a Mechanical Assault Skeleton Suit against alien creatures called Quarks. Players act as commanders of a private military company, building and customizing mechanical suits before taking them into combat. Suit parts are separated between equipment that affects status and parts used for appearance, so visual customization does not depend on combat values. Movement includes boosters for rapid traversal and attacks across battlefields. Combat includes groups of Quarks and larger creatures that pursue the player aggressively. Weapons can also be visually and mechanically customized by combining hundreds of parts. The game includes a setting about humanity’s war for survival after unknown creatures appear and devastate settlements.
