・This form is a Woundwort, the focal point of the weapon system known as “Gundam TR-6,”
equipped with one Hrududu II Support G-Part each on its upper and lower halves.
・The “Hrududu II” is a collection of support parts,
including a Shoulder Unit with built-in thrusters and a generator, and an augmented Skirt Unit,
equipped with a Spread Beam and attitude control verniers.
These parts were attached to a Gundam TR-6 body unit to create the Woundwort Rah II.
・For armaments, it is equipped with two boosted rifles featuring heat blades and claw functions.
The rifle can fire various beam rounds and possesses high beam resistance due to its built-in I-Field.
When properly employed in medium to close-range combat, it can achieve significant results.
・Furthermore, this unit represents the culmination of the “TR Project”,
which expanded functionality into ultra heavy equipment like massive ballistic weapons
and large MA forms for hit-and-run tactics.
It ultimately evolves into the decisive weapon, the final form of the Gundam TR-6.
・Can be deployed both on the Ground and in Space.

New reward MS for Clan Match is available from [PST] 01/03/2026 / [CET] 01/03/2026.
■New MS
・★★ Act Hizack (General unit, ground/space uses, cost: 400)
■Mobile Suit Features
・General unit with cost of 400.
・A Hizack variant featuring specifications from the Newtype Lab,
which was established by Federation Forces after the One Year War.
・The Hizack is a mass-production MS commissioned to former Principality of Zeon engineers
for development by Federation Forces after the One Year War.
While its external appearance resembles that of the Zaku,
its internal layout was redesigned to incorporate Federation technology.
・Due to post-war reparations and public demand for military downsizing, cost reduction was made a priority,
resulting in difficulties with simultaneous beam weapon usage and other issues.
In spite of this, the Hizack’s cockpit featured a panoramic monitor and linear seat
such standard requirements for second-gen MSs, and was produced in large numbers as a primary unit.
・This unit was operated by Titans during the Gryps War.
While based on the Hizack, it was designed for mid-range support roles,
working in coordination with captured Act Zakus and transformable MAs.
It is equipped with reliable ballistic weaponry and has undergone internal upgrades,
including magnetic coating, earning it the designation of “Act Hizack”.
・Can be deployed both on the Ground and in Space.
※Since the lineup has been updated, “Condition of claiming Clan Match reward MS” has been reset as well.
The latest information will be posted on STEAM News and our X (Twitter) in the future.

・★★★★ Woundwort Rah II LV1 (Raid unit, ground/space uses, cost: 550)
※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features
・Raid unit with cost of 550.
・This form is a Woundwort, the focal point of the weapon system known as “Gundam TR-6,”
equipped with one Hrududu II Support G-Part each on its upper and lower halves.
・The “Hrududu II” is a collection of support parts,
including a Shoulder Unit with built-in thrusters and a generator, and an augmented Skirt Unit,
equipped with a Spread Beam and attitude control verniers.
These parts were attached to a Gundam TR-6 body unit to create the Woundwort Rah II.
・For armaments, it is equipped with two boosted rifles featuring heat blades and claw functions.
The rifle can fire various beam rounds and possesses high beam resistance due to its built-in I-Field.
When properly employed in medium to close-range combat, it can achieve significant results.
・Furthermore, this unit represents the culmination of the “TR Project”,
which expanded functionality into ultra heavy equipment like massive ballistic weapons
and large MA forms for hit-and-run tactics.
It ultimately evolves into the decisive weapon, the final form of the Gundam TR-6.
・Can be deployed both on the Ground and in Space.

■Update for Clan Match reward MS!
New reward MS for Clan Match is available from [PST] 01/03/2026 / [CET] 01/03/2026.
■New MS
・★★ Act Hizack (General unit, ground/space uses, cost: 400)
■Mobile Suit Features
・General unit with cost of 400.
・A Hizack variant featuring specifications from the Newtype Lab,
which was established by Federation Forces after the One Year War.
・The Hizack is a mass-production MS commissioned to former Principality of Zeon engineers
for development by Federation Forces after the One Year War.
While its external appearance resembles that of the Zaku,
its internal layout was redesigned to incorporate Federation technology.
・Due to post-war reparations and public demand for military downsizing, cost reduction was made a priority,
resulting in difficulties with simultaneous beam weapon usage and other issues.
In spite of this, the Hizack’s cockpit featured a panoramic monitor and linear seat
such standard requirements for second-gen MSs, and was produced in large numbers as a primary unit.
・This unit was operated by Titans during the Gryps War.
While based on the Hizack, it was designed for mid-range support roles,
working in coordination with captured Act Zakus and transformable MAs.
It is equipped with reliable ballistic weaponry and has undergone internal upgrades,
including magnetic coating, earning it the designation of “Act Hizack”.
・Can be deployed both on the Ground and in Space.
※Since the lineup has been updated, “Condition of claiming Clan Match reward MS” has been reset as well.
The latest information will be posted on STEAM News and our X (Twitter) in the future.
