Instead, the company moved on 　　　　to develop mass-production units by cutting its excessive performance mechanisms. 　　　・To counter this, engineers at OZ secretly started researching a method 　　　　of forcibly enhancing a pilot's combat capabilities 　　　　by directly transmitting actions necessary for victory to the brain, 　　　　resulting in the completion of the ZERO System to boost pilot performance. 　　　　Along with this, they would upgrade materials, equipment, and structure. 　　　　For armor, they would use a new material known as Gundanium alloy, 　　　　offering remarkable bulletproofing and viscosity, 　　　　and enabling the unit to transform into a high-speed Neo-Bird form. 　　　　They would also successfully develop the Twin Buster Rifle, 　　　　capable of annihilating an entire colony with a single shot. 　　　・However, fearing this technology would be exploited by OZ, 　　　　the engineers abandoned the unit and fled the company. 　　　　Once rebuilt, this MS would make an appearance in A.C. 195, which was a time of great turmoil. 　　　・Can be deployed both on the Ground and in Space. https://bo2.ggame.jp/images/info/2026/08/33bc8d9f098a49942b9323eeeae337c6.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 “ZERO System LV1” 　　　・When the ZERO System is active, temporarily trigger the following effects. 　 　　　　・Unit’s ATK power and mobility are increased 　　　　・Unit’s max melee and ranged strengths are increased 　　　　・The amount of thruster consumed at the start of and during High Speed Movement is reduced 　　　　・Main ranged weapon can be used during High Speed Movement 　　　　・Target weapon’s performance is altered 　　　　・Damage from enemy attacks and stagger caused by cumulative damage are reduced 　　　　・The Flap Booster LV2 skill is provided 　　　　・Time of locked-on by psycommu weapon is extended 　　　　When the effect ends, the thrusters become overheated. 　 　　　Sub-weapon “Split TB Rifle [Discharge]” 　　　・Can only be used while the ZERO System skill is in effect. 　　　　Deals damage while discharging, penetrating MS on hit, 　　　　and can also be used in midair, but must stop to fire. 　　　　Requires focus, and can move while focused 　　　　Note that modifier is not applied while in a crouched position.
