・Melee strength and maximum limit
・Ranged strength and maximum limit
・Ballistic resistance and maximum limit

we have adjusted existing skill performance to better support a variety of playstyles.
◎Adjusted Expansion Skills
▼Attack-Type Expansion Skills
Ranged Strength Expansion
Melee Strength Expansion
The increase values per LV have been raised, and the maximum LV has been increased.
▼Defense-Type Expansion Skills
Ballistic Resistance Expansion
Beam Resistance Expansion
Melee Resistance Expansion
Value is now increased in LV4 and 5.

⇒ The expansion skill list can be accessed from the Skill Development screen
by pressing the "Expansion skill list" button.
◎Additional improvements have been made to the Expansion Facilities.
⇒ To further improve the usability and visibility of the expansion facilities,
the following improvements have been made.
■Improved the system behavior when a lower-LV skill of the same type is developed
⇒ If an expansion skill of the same type as the currently equipped one is developed,
lower-LV versions of that skill will now be displayed in grey and will no longer be selectable.
■Revamped the sub-items in the MS List screen
⇒ Extension skills were previously accessed under “Enhancement List”, but the name was unclear,
so it has been renamed “Enhancement/Expansion List”.
■Refined the animation for developing LV5 expansion skills
⇒ The animation for developing an extension skill at LV5, the maximum level,
has been updated to improve visibility.
■Adjusted confirmation dialog during extension skill enhancement
⇒ In the confirmation dialog displayed when enhancing an extension skill,
the initial cursor position has been moved to “Cancel” to help prevent misoperations.
■Improved selection display for maintenance engineers
⇒ The selection options for maintenance engineers during extension skill development were hard to see,
so the item frames now glow to improve visibility.

■Fixes
◎Units
・Fixed an issue in “RF Kämpfer” where the sub-weapon “Incom Unit x4”
sometimes did not return to the player’s unit.
・Fixed an issue in “RF Kämpfer” where the sub-weapon “3-Barrel Heat Wire”
sometimes caused the launch sound effect to loop continuously.
・Fixed an issue in “Mass Production Type Nu Gundam” where the sub-weapon “Incom Unit x4”
sometimes did not return to the player’s unit.
・Fixed an issue in “Hi-Nu Gundam” where the sub-weapon “Fin Funnel [Support]”
sometimes did not operate correctly on certain units under specific actions.
・Fixed an issue in “Destiny Gundam” where the “Hyper Deuterion Engine” sound effect could continue playing
after leaving its effect area.
・Fixed an issue in “F90II [Ⅰ Type]” and “F90 Type I [Jupiter Battle]” where under certain conditions,
the lance portion’s hit detection would disappear during the skill “Flight Shield Attack”.
◎Skills
・In the partial skill description for the skill “High-Performance Thruster Control System”,
there were sentences whose wording differed by level (LV), so they were standardized now.
■Corrected description
Skill LV1: High speed movement with slightly less thruster consumption and additional actions
can be performed while jumping as well.
Skill LV2: High speed movement with less thruster consumption and additional actions
can be performed while jumping as well.
Skill LV3: High speed movement with lower thruster consumption and additional actions
can be performed while jumping as well.
⇒ The wording has been unified to “slightly less thruster consumption” across all skill levels.
The above effect is identical across all skill levels and does not vary by Skill LV.
◎MAPs
・Fixed an issue in “Colony Drop Area” where pilots could become trapped on objects near Relay Point D.
The latest information will be posted on STEAM News and our X (Twitter) in the future.

◎You can now view a list of expansion skills available for development.
⇒ Along with the addition of new expansion skills,
a new feature has been added that allows you to view all developable expansion skills in a list.
⇒ The expansion skill list can be accessed from the Skill Development screen
by pressing the "Expansion skill list" button.
◎Additional improvements have been made to the Expansion Facilities.
⇒ To further improve the usability and visibility of the expansion facilities,
the following improvements have been made.
■Improved the system behavior when a lower-LV skill of the same type is developed
⇒ If an expansion skill of the same type as the currently equipped one is developed,
lower-LV versions of that skill will now be displayed in grey and will no longer be selectable.
■Revamped the sub-items in the MS List screen
⇒ Extension skills were previously accessed under “Enhancement List”, but the name was unclear,
so it has been renamed “Enhancement/Expansion List”.
■Refined the animation for developing LV5 expansion skills
⇒ The animation for developing an extension skill at LV5, the maximum level,
has been updated to improve visibility.
■Adjusted confirmation dialog during extension skill enhancement
⇒ In the confirmation dialog displayed when enhancing an extension skill,
the initial cursor position has been moved to “Cancel” to help prevent misoperations.
■Improved selection display for maintenance engineers
⇒ The selection options for maintenance engineers during extension skill development were hard to see,
so the item frames now glow to improve visibility.

■Fixes
◎Units
・Fixed an issue in “RF Kämpfer” where the sub-weapon “Incom Unit x4”
sometimes did not return to the player’s unit.
・Fixed an issue in “RF Kämpfer” where the sub-weapon “3-Barrel Heat Wire”
sometimes caused the launch sound effect to loop continuously.
・Fixed an issue in “Mass Production Type Nu Gundam” where the sub-weapon “Incom Unit x4”
sometimes did not return to the player’s unit.
・Fixed an issue in “Hi-Nu Gundam” where the sub-weapon “Fin Funnel [Support]”
sometimes did not operate correctly on certain units under specific actions.
・Fixed an issue in “Destiny Gundam” where the “Hyper Deuterion Engine” sound effect could continue playing
after leaving its effect area.
・Fixed an issue in “F90II [Ⅰ Type]” and “F90 Type I [Jupiter Battle]” where under certain conditions,
the lance portion’s hit detection would disappear during the skill “Flight Shield Attack”.
◎Skills
・In the partial skill description for the skill “High-Performance Thruster Control System”,
there were sentences whose wording differed by level (LV), so they were standardized now.
■Corrected description
Skill LV1: High speed movement with slightly less thruster consumption and additional actions
can be performed while jumping as well.
Skill LV2: High speed movement with less thruster consumption and additional actions
can be performed while jumping as well.
Skill LV3: High speed movement with lower thruster consumption and additional actions
can be performed while jumping as well.
⇒ The wording has been unified to “slightly less thruster consumption” across all skill levels.
The above effect is identical across all skill levels and does not vary by Skill LV.
◎MAPs
・Fixed an issue in “Colony Drop Area” where pilots could become trapped on objects near Relay Point D.
The latest information will be posted on STEAM News and our X (Twitter) in the future.
