■Notice of Supply Drop Lineup “Crossbone Gundam X-3” Supply Drop Lineup has been updated.
■Added New Materials ■Unit ・★★★★★ Crossbone Gundam X-3 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. ・The third unit of the Crossbone Gundam series, supplied to the Crossbone Vanguard space pirates by Buch Concern. ・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. ・Although there is no difference in performance compared to the X1 or X2, features like an additional Gatling Cannon positioned inside its thickened chest armor emphasize close-combat capabilities. ・For defensive purposes, it is equipped with I-Field generators that are highly effective against battleship-class beam attacks. For offensive purposes it wields the Muramasa Blaster, which not only fires beams but also generates 14 beam sabers along its sword-like edge for powerful melee combat, making it exceptional in both offense and defense. However, despite its remarkable effectiveness, there are risks associated with its limited operation time, making it a highly difficult unit to operate. ・Can be deployed both on the Ground and in Space. https://bo2.ggame.jp/images/info/2026/02/2312fd8213e3b7a09b0389effd4a30b4.mp4

Skill “Max Output (T)” ・When dealing damage to an enemy MS with a melee weapon, the Skill Gauge increases. Pressing "special weapon" when the skill gauge is full activates the skill, granting the following effects for a set duration. ・Fully recovers HP for all parts (head, back, legs) while activation ・Increases unit attack power, mobility ・Damage taken from melee attacks is reduced ・The upper limit of high-speed movement speed increases, thruster consumption when initiating high-speed movement and during high-speed movement is reduced ・Performance for weapons compatible with the skill is altered This skill can be used again after some time has passed.
Skill “Heavy Attack Kai” ・When selecting a weapon that supports this skill, hold and release the attack button to perform a melee attack with added power. ・Increases the attack power and close combat accuracy ・Negates enemy MS’s “Special Cushioning” skill ・Even when hitting an enemy MS’s shield weaponry, deals damage to the MS itself ・During Heavy Attack, reduces damage taken when attacked, damage reaction, and stagger caused by accumulated damage ・Also, Heavy Attack can be used while in midair
Sub-weapon “X-3 I-Field Generator” ・Temporarily generates an arm I-Field, which reduces HP damage from beam attacks and reduces or nullifies reactions. Reactions from cumulative beam attacks are reduced as well. ・If this weapon is selected while its arm I-Field is activated, and ranged beam attacks are taken from the front, cumulative damage reactions from those attacks are nullified. ・Also compatible with the Max Output (T) skill, extending the weapon’s effect time during max output. ・However, changing to melee and exiting during a tackle will cause the I-Field to vanish, resulting in overheating.
