30MM W-03 Multi Booster Unit is an early 30 MINUTES MISSIONS option set designed to replace the standard lower legs of compatible 1/144 ExAMACS with booster-equipped units. Released in August 2019, it was created specifically to work with both Alto and Portanova, giving either of the two original 30MM mass-production machines a more specialised mobility-focused lower-body configuration.
The set contains a matched left-and-right pair of leg units and is intended as a direct parts swap rather than a complete mecha kit. Because it uses the same modular construction philosophy as the wider 30MM range, the parts are also useful as components for compatible custom builds beyond the two originally specified machines.
