As commander of a private military company, you pilot a Mechanical Assault Skeleton Suit (M.A.S.S.) in a war against the alien creatures known as Quarks. The campaign sends you into battle to help defend humanity.
Fight groups of enemies and larger, more aggressive foes with ranged and melee weapons. Boost across battlefields to move and attack, and shape your approach with combat builds and upgrades.
Customize your mech’s appearance with armor parts, paint, and accessories, while its looks are kept separate from stat-bearing equipment. Build weapons from component parts, then earn blueprints and resources in missions to unlock more parts and progress through upgrade trees.
Many supplied reviews praise the extensive mech customization, especially the freedom to shape a machine’s appearance and create personal designs. Weapon customization and seeing creations in missions also appeal to some players. Reviews are much more divided on combat: some enjoy its melee action or straightforward mission loop, while many describe fights as clunky, repetitive, or lacking impact. Repeated complaints also mention the grind for unlocks, lengthy dialogue, and concerns about developer updates.
