■Added New Materials
■Unit
・★★★ Amakusa LV1 (General unit, ground/space uses, cost: 700)
※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features
・General unit with cost of 700.
・This unit was developed under the restructured Jupiter Empire,
after analyzing the data obtained from a captured Crossbone Gundam X-2.
However, the Jupiter Empire’s technological limitations,
combined with the high level of difficulty involved in analyzing independently-developed technologies,
led to complications in reproducing it.
Although the resulting machine was said to surpass the original Crossbone Gundam in overall specifications,
the MS’s body size increased to a conventional 18-meter class,
far larger than the compact form of its predecessor.
・In addition to standard weaponry such as a beam rifle and beam saber,
the unit is also equipped with close-combat armaments including a hyper hammer and claws.
The combat performance of units within Jupiter’s Imperial Forces was enhanced by equipping them
with a high-speed computational processing device using biological components, known as the “Bio Brain”.
The Amakusa in particular utilized combat data from a pilot recognized as the most powerful Newtype
during the One Year War, enabling it to exhibit extraordinary power.
・Can be deployed both on the Ground and in Space.

※This video may not be representative of the actual product.
※Please also make sure to have a check to the event schedule so that you will not miss anything.
Skill “Bio Brain Control System”
・When the unit’s HP falls below a certain threshold, this skill automatically activates only once,
granting the following effects for a set duration:
・ATK and mobility are increased
・Thruster gauge consumption is reduced when activating high speed movement
・High speed compatible weapons can be used
・Gain the skills “Forced Injector LV4”, “Emergency Avoidance LV3”, and “Power Accelerator LV3”
・Nullifies all reactions except for knock-back due to cumulative damage, ONLY at the moment of skill activation

■Fixes
◎Units
・In “Wing Gundam Zero [EW]”, an issue was fixed where under certain conditions, attacks performed
using the skill “Aerial Melee System” could have their post-attack motion canceled by jumping.
・In “Heavygun”, an issue was fixed where the MS model could behave unnaturally when using the skill
“Emergency Evasion System”.
・In “G-Cannon Magna”, an issue was fixed where the MS model could behave unnaturally
when using the skill “Resist Move”.
・In “Jegan [Birnam Type]”, the MS name was incorrect when using the English language setting,
so it has been corrected.
・Fixed an issue where Destiny Gundam’s Arondight Beam Sword aerial melee animation
during skill "Max Performance (S)" could behave differently compared to other platform versions.
・In “Burning Gundam”, an issue was fixed where the damage reaction reduction effect would not activate
under certain conditions when charging the skill “Heavy Attack (D)”.
◎Battles
・In “F90II [Ⅰ Type]”, when transitioning into an attack stance using the skill “Flight Shield Attack”,
the sub-weapon “Fin Funnel [Support]” from “Hi-Nu Gundam” was incorrectly performing support fire
and this issue has been fixed.
※Since the “Fin Funnel [Support]” is a weapon that links with “damage-dealing armaments”, excluding Tackle,
Counter, and Psycommu weapons, the attack stance activated by a skill effect is not included in this linkage.
