■Added New Materials
■Unit
・★★★ Zeta Gundam LV1-2 (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 Zeta Gundam is equipped with an I-field claw and a bladed I-field blaster.
・Zeta Gundam serves as the AEUG’s flagship model
and was completed as a prototype mobile suit under Project Zeta.
Thrusters along the suit’s body can all swivel to face the same direction,
using the total thrust available to the suit to improve mobility,
allowing for sub-flight caliber high speed hit-and-run maneuvers.
・Gundarium Alloy and a movable frame allow the suit
to transform into a configuration known as the Waverider,
which can enter the atmosphere unassisted and achieve flight under gravity.
Additionally, since the suit’s thrust can exceed its mass ratio, a Bio-Sensor,
which is a simpler version of the Psycommu, was secretly installed to assist with controls.
・Overall, this equipment variant’s claw-shaped I-field generator
and blade that doubles as a beam rifle provide enhanced capability in sustained combat
and a significant boost in battle power.
・Can be deployed both on the Ground and in Space.
