 ■Added New Materials
  ■Unit
  ・★★★★ Destiny Gundam 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.
  ・Following the Second Alliance-PLANT War, an armed organization of Coordinators known as ZAFT developed
   this "Second Stage Series" mobile suit as its flagship unit, secretly implementing a nuclear engine,
   after the signing of the Junius Treaty.
  ・Known as the Destiny Gundam, this unit features a combination of all silhouette weaponry systems
   previously used for Impulse Gundams, including the mobility-focused Force, melee-focused Sword,
   and artillery-focused Blast systems. The successful implementation of these capabilities is largely due to
   adopting a nuclear engine with an ultra-compact reactor, as well as a hybrid Hyper Deuterion Engine
   compatible with the Deuterion Beam Energy Transfer System for enhanced battery functionality.
  ・It carries a diverse array of weaponry including the palm-mounted beam cannon “Palma Fiocina Palm B Cannon”,
   the reticle-guided beam boomerang “Flash Edge”, the large beam sword “Arondight”, beam rifles
   and high-energy long-range beam cannons.
   It possesses high resistance to solid projectiles via the “Variable Phase Shift Armor” skill,
   yet shifts to more aggressive performance when the “Max Performance (S)” skill is active.
   While demanding advanced piloting skills, mastering these capabilities promises significant combat effectiveness.
  ・Can be deployed both on the Ground and in Space.

   Skill "Max Performance (S)"
   ・When the unit's HP falls below a certain level, this skill activates automatically once,
    granting the following effects for a certain duration.
    ・Attack and mobility increase.
    ・Reduces thruster consumption when starting high-speed movement.
    ・Reduces damage taken and stagger due to cumulative damage during high-speed movement.
    ・Grants the skill “Offense System LV1”.
    ・The performance of skill-compatible weapons will be altered.
     When moving forward at high speed while a compatible weapon is selected,
     an Assault Stance is taken, staggering and damaging all enemies collided with.
    ・Upon skill activation, HP for all body parts (head, back, legs) is fully restored
     and all reactions except for knockback due to cumulative damage are nullified.

 
   Skill "Hyper Deuterion Engine"
   ・When an ally beacon is within a 300m radius, and your unit is not attacking,
    thruster recovery and thruster overheat recoveryspeeds will increase.
    This skill only applies when a pilot is on board the MS, and its radar has not been jammed.
 
   Skill "Variable Phase Shift Armor"
   ・When attacked by ballistic ranged weapons, damage and stagger caused by cumulative damage are reduced.
    If head, legs, or back are attacked, there is an additional reduction in damage.
    Additionally, reduces leg strain upon landing or post high-speed movement.

■Fixes
 ◎Units
  ・In Tallgeese III, the right shoulder Mega Cannon would sometimes behave unnaturally under certain conditions,
   so this has been fixed.
  ・In Tallgeese III, a typo in the unit’s description has been corrected.
  ・In Wing Gundam Zero [EW], the sub-weapon “Split TB Rifle [Discharge] [EW]” could
   sometimes behave unnaturally under certain conditions, so this has been fixed.
  ・In GM Shooter, the main ranged weapon “GM Shooter LBR” could sometimes be fired without consuming
   the heat gauge under certain conditions, so this has been fixed.
  ・In Prototype Kämpfer, the unit’s name has been corrected for the Traditional Chinese (Hong Kong) and
   Traditional Chinese (Taiwan) language settings.
 
 ◎Skills
  ・The “CS Booster I-Field” skill’s beam damage reduction effect was not activating
   when hit by beam attacks that “negate Special Cushioning’s reduction effect”, so this has been fixed.
  ・In the “Aero Armor” skill, the skill description was overflowing its text box when the language was set to English,
   so this has been fixed.
 
 ◎Custom parts
  ・The custom part “Test Type Irregular DBL” was eligible for auto-equipping despite containing negative effects,
   so this has been fixed.
 
The latest information will be posted on STEAM News and our X (Twitter) in the future.
