FA-178 Full Armor Gundam Mk-II (Tech lv9 / All)

MSZ-006A1 Zeta Plus A (Tech lv11 / Land-Flight)
A Zeta Gundam variant redesigned for atmospheric use. A small production run by Karaba saw combat. The Zeta Plus A carried a variety of weapons loadouts; represented in GNO3 is the beam rifle type.

RMS-141 Xekueins Type I (Tech lv10 / All)
An all-around mass production MS developed by the Titans. Equip-able with a wealth of weaponry, it could change gear with a parts swap. The Type I mounted a beam rifle.

RMS-141 Xekuzwei (Tech lv11 / All)
A heavy MS developed by the Titans. Developed with the twin goals of mobility and functionality as a heavy weapons platform, this extra-large MS pushes the boundary between suits and armors in both appearance and capabilities.

MS-14J Regelgu (Tech lv9 / Space)
A refined version of the Principality's Gelgoog. Great leaps in mobility were made with its shoulder armor's modification into wing binders, resulting in a suit which can keep up with modern MDes.

AMX-109 Capule (Tech lv11 / Amphibious)
An amphibious MS developed by Neo Zeon's military. Further refining the Principality's Gogg project for a high-performance amphibious suit, a small amount were manufactured as part of plans for a landing.
