■New unit
・★★★ Guntank R-44 LV1-4 (Support unit, ground/space uses, cost: 550+)
※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features
・Support unit with cost of 550.
・A restored mobile suit prototype, said to have been developed as part of the Formula Project,
which aimed to miniaturize units.
・It was designed to combine the long-range bombardment capabilities of the G-Bull
with the functionality of a transformable MS.
However, its miniaturization led to an overall drop in performance,
and it was eventually scrapped without being officially approved for manufacture.
But former Federation brigadier general Roy Jung privately acquired the unit,
preserving its weaponry and ammunition while modifying various components
in preparation for emergencies.
While this unit only has ballistic ranged armaments,
such as 200mm canon, missile pod and finger launcher.
・Jung piloted this unit during the Crossbone Vanguard assault,
and it was eventually displayed at the war museum where he served as curator.
Yet his efforts were limited to those of a military enthusiast,
and failed to contribute meaningfully to the resistance.
This unit's name and model number are not official,
deriving instead from Jung's age of 44 at the time of acquisition.
・Can be deployed both on the Ground and in Space.

■Added New Materials
■Unit
・★★★★★ Crossbone Gundam X-1 FC LV1 (General unit, ground/space uses, cost: 750)
※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features
・General unit with cost of 750.
・This unit is a significantly enhanced version of the Crossbone Gundam X-1 Kai Kai (Skullheart),
with a focus on improved defensive capabilities, created for the Jupiter Battle of UC 0136.
The Crossbone Gundam is an experimental prototype unit based on the F9 series concept,
equipped with four large movable thrusters on its back,
allowing it to freely alter its mobility vectors to cope with the Jupiter Sphere's high gravity.
・After the Jupiter War, the leader of the new Jupiter Empire launched Operation Divine Thunder,
firing an ultra-long-range colony laser at Earth from the Jupiter Sphere.
This unit was used in Operation Steel 7 to counter the attack.
・Its frame, featuring built-in thrusters for explosive acceleration,
was lined with all remaining ABC cloaks (anti-beam coating cloaks) for extra protection.
This, combined with shoulder armor that is equipped with four X-3 I-Field generators,
provided the unit with remarkable anti-beam resistance.
Such robust defenses made it possible for a small squadron of these units
to cut through a large contingent of enemy forces.
・Can be deployed both on the Ground and in Space.

Skill "Max Output (T) LV2"

・Increases unit attack power, mobility.
・All weapons will negate the damage reduction effects of enemy special buffers
and even when attacks hit a shield, damage will still be dealt to the main unit.
・Increases High Speed Movement max limit,
and reduces the amount of thruster consumed while moving at high speed.
・Damage reactions caused by ranged attacks received during melee attacks are nullified
and incoming damage is reduced.
・Performance for weapons compatible with the skill is altered.
This skill can be used again after some time has passed.

Skill "X-1 Full Cloth"
