■Added New Materials
■Unit
・★★★★★ Crossbone Gundam X-2 Kai LV1 (Raid unit, ground/space uses, cost: 750)
※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features
・Raid unit with cost of 750.
・A partially modified variant of the Crossbone Gundam X-2, a flagship to the Crossbone Vanguard space pirates.
・The Crossbone Gundam X-2 is the second prototype model manufactured by
the Strategic Naval Research Institute (S.N.R.I.), developed based on the F9 series concept.
It features four large, movable thrusters on its back, and its flexible thruster binders allow it to be operable
within the powerful gravity of Jupiter’s atmosphere.
In terms of performance, the X-2 has no significant differences compared to the X-1,
but it is painted jet black in homage to the color scheme of the Black Vanguard squadron units,
one of which was formerly operated by its pilot Zabine Chareux.
・After defecting from the Jupiter Empire, this unit was restored using the empire’s technology,
including its lost weaponry and Core Fighter.
In spite of its enlarged rear thrusters, there is no improvement in propulsion performance,
a testament to the challenges involved in replicating a machine built with a different technological system.
・Can be deployed both on the Ground and in Space.

・Performance for weapons compatible with the skill will be altered,
nullifying reaction to attacks taken while executing a stopped attack, and reducing damage.
Can be used again after some time has passed.
Sub-weapon “Buster Launcher [Max Output]”
・Can only be used for focused firing, still you can focus while moving.
Must stop to fire, but have a decent firing rate and shield penetration effect.
Compatible with Max Output (Z) skill, some enemy beam resistance is nullified,
