  [CEST] 08/28/2025 10:00 – 09/04/2025 06:30 [Scheduled]
 
 ■Added New Materials
  ■Unit
   ・★★★★ Wing Gundam Zero [EW] LV1 (Raid unit, ground/space uses, cost: 700)
    ※The above MS is eligible for the Monthly MS Bonus Unit.
 
  ■Mobile Suit Features
   ・Raid unit with cost of 700.
   ・This unit served as a prototype for the five Gundams deployed in Operation Meteor,
    a resistance operation against the growing military power of OZ within the United Earth Sphere Alliance.
   ・The After Colony (A.C.) calendar began with humanity’s colonization of space. In A.C. 195,
    following the end of war between Earth nations and the colonies,
    the United Earth Sphere Alliance was established, advocating for Total Pacifism.
    But Dekim Barton, head of the Barton Foundation, a key player in space-based capital, secretly formed
    the Mariemaia Army, a private military organization, to resume efforts to dominate the Earth Sphere.
   ・This unit is equipped with the ZERO System, which directly transmits combat data to the pilot’s brain,
    enhancing their abilities.
    The Wing Binders mounted on its back provide vernier thrust for high-speed movement,
    and can also serve as defensive shields.
    It is also armed with the Twin Buster Rifle, capable of annihilating a colony in a single shot,
    making it ideal for hit-and-run tactics during strategic base assaults.
    This Gundam played a crucial role in liberating the Presidential Palace occupied by the Mariemaia Army.
   ・Can be deployed both on the Ground and in Space.

   Skill “Aerial Boost”
   ・Can be used in the air.
    Pressing the touchpad during a jump or while descending will consume thrust and perform a jump.
    Movement speed is increased and damage from ranged attacks is reduced when jumping
    while this skill is active, but performing certain actions cancels the latter effect.
    More thrust is consumed when using this skill in succession.

 
   Skill “ZERO System” LV2
   ・After activating the sub-weapon “Activate ZERO System”, the following effects occur for a limited time.
    ・Attack power and mobility are increased
    ・Max melee and ranged strengths are increased

    ・The “Enhanced Offense System LV1” skill is granted
    ・Damage from enemy attacks and stagger caused by cumulative damage are reduced
    ・Psycommu lock-on time is extended
    ・Performance of compatible weapons are enhanced
    After the effect ends, thrusters will be overheated.
 
   Skill "Emergency Self-Destruct Program"
   ・When your unit is destroyed,
    the explosion deals damage to the enemy unit's overall HP and to all of their parts.
    Note that this skill will not activate if you are not on board the MS when it is destroyed.
 
   Sub-weapon “Split TB Rifle [Discharge] [EW]”
   ・Requires focus, and can move while focused, but must stop to fire.
    Deals damage while discharging, penetrating MS on hit.
    It can also be used in the air, though the crouching bonus does not apply.
    When the “ZERO System” is activated, the weapon’s performance changes
    and the crouching bonus will be applied.
 
    ◎Before activating “ZERO System”
     ・Fires a non-staggering beam while spinning in place, attacking in all directions.

     ・Fires a staggering beam in the reticle’s direction.
