■Mobile Suit Features ・General unit with cost of 700. ・A compact melee-oriented MS developed under the Formula Project as a return to the fundamentals of battlefield tactics. ・As 5th-generation MS production costs rose, the Federation’s Strategic Naval Research Institute (S.N.R.I.) started the Formula Project to re-envision mobile suits with their original design as versatile humanoid war machines in mind. ・Stripped of superfluous integrated weapons systems, this minimalist MS uses micro-honeycomb technology to slim down the armor and movable frame, reducing size and weight to put the “mobile” back in “mobile suit”. In addition, it boasts 1.5 times the output of conventional MS thanks to two miniaturized generators. ・It also features mission pack system hard points for increased versatility. A holo-cube processor is used for complex controls, and some even speculate that it has an artificial personality processing system on board. ・Can be deployed both on the Ground and in Space. https://bo2.ggame.jp/images/info/2025/03/76183a790a77bd92469593bac569dc14.mp4

Sub-weapon “F90 Shield” ・High defense and constant coverage, but decrease mobility performance. Selecting this weapon during battle allows the shield to be positioned in front. Damage taken by the shield will be reduced while selected. You can attack with the shield when selecting it, and using a shield attack to repel enemy MS melee weapons or melee attacks (except tackles or heavy attacks) from the front can knock the enemy down. In addition, deal damage to enemy MS if the shield attack hits on them. Note that shield attacks cannot be used in combo attack, and the shield cannot be used if it is destroyed.

■Notice of Supply Drop Lineup "F91" Supply Drop Lineup has been updated.
■Added New Materials ■Unit ・★★★★★ F91 LV1 (General unit, ground/space uses, cost: 750) ※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features ・General unit with cost of 750. ・This compact MS was created by the Strategic Naval Research Institute (S.N.R.I.) under its initiative to increase the role of compact mobile suits and realize the full potential of current technology. ・Based on concerns that the increased size of 5th-generation MS would lead to higher costs due to the impossibility of repurposing existing components, S.N.R.I. devised the Formula Plan to downsize mobile suits. The preceding F90 series had multi-functional armor(MCA) and newly-developed thermonuclear reactors, greatly improving the thrust-to-weight ratio. This extra output was used to power a Variable Speed Beam Rifle (V.S.B.R.) with the ability to adjust rate of fire and firepower, as well as a beam shield. ・This MS uses data obtained from the F90 to realize the full potential of current technology by improving the maximum output. Limiters have been imposed due to its extraordinary capabilities, but it comes equipped with a biocomputer that activates the suit’s full potential only when the pilot is deemed capable of handling it. ・Can be deployed both on the Ground and in Space. https://bo2.ggame.jp/images/info/2025/03/2f89d4603eee7677c76542d484a78153.mp4
※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 “Max Performance” ・This skill can be activated by pressing the "special weapon" after a destroying a certain number of enemy MS or destruction assists. ・All the parts HP (head, back, and legs) of the MS will be fully recovered. ・Increases the unit attack power and mobility. ・Thrusters consumption at the start of and during high-speed movement is also reduced. ・Delays the movement of your MS’s marker on enemy radar After the skill effect ends, it can be used again after a certain cooldown period. https://bo2.ggame.jp/images/info/2025/03/5889068ff1c80961779a8974b734ff12.mp4
Skill “Mobile Melee Program” ・Activates while moving forward at high speed for a certain time with target weapon selected. Melee attacks switch to special melee while activated. However, during melee attacks activated by this skill, thruster recovery will not occur. ※For the F91, the corresponding weapon for this skill is the sub-weapon “F91 Beam Saber x2”.
Sub-weapon “F91 Beam shield” ・When selecting this weapon, your MS will activate a beam shield that can attack or defend. While selected, shield attacks become possible, allowing you to deflect melee attacks from the front, except for projectile-based melee attacks, tackles, and heavy attacks from enemy MSs, causing them to be knocked down. Additionally, it will deal damage if hitting an enemy MS. However, shield attacks cannot be performed in combo attacks. ・The Beam Shield differs from a physical shield in the following ways: ▼Beam Shield ・The shield will only be available while the weapon is selected. ・When blocking ranged attacks, damage to MS HP is reduced. ・It has a limited usage time and will overheat if exceeded. ・If the shield’s HP reaches zero, it will forcefully overheat. ・Once the overheat recovers, it can be used again with full shield HP restored. ・Deploying the shield does not negatively affect mobility. ▼Physical Shield ・Always has a shield hitbox. ・If the shield is selectable, damage taken by the shield is reduced while selected. ・When the shield’s HP reaches zero, it is destroyed and loses its defensive effects. ・While the shield is intact, mobility is slightly hindered, but this restriction will be lifted when the shield is destroyed.

■Mobile Suit Features ・Raid unit with cost of 650. ・A prototype unit created to demonstrate the ZZ Gundam’s transformation mechanism. ・The original plan called for a Core Top and Core Base configuration, but the design was hastily changed to a three-unit formation with a Core Block system added for the safety of the pilot. For this reason, the transformation from MS form to Fortress form was not possible. ・This unit was equipped with a newly-developed high-output compact generator producing power comparable to the ZZ Gundam during the various tests. Also, it was modified with a head featuring a prototype High Mega Cannon, and outfitted with a Double Cannon designed for use as both a melee weapon and a firearm. ・Based on the test results of this prototype, development of the ZZ Gundam was underway to eventually be deployed in a final battle against the Titans. However, practical implementation of its new high-output weapons was delayed, and the unit was only completed once the Gryps War had already ended. ・Can be deployed both on the Ground and in Space. https://bo2.ggame.jp/images/info/2025/02/765e3a1539a7356c8b645ceda8cf8180.mp4
