■Unit
・★★★ Prototype Psycho Gundam LV1 (General unit, ground/space uses, cost: 650)
※The above MS is eligible for the Monthly MS Bonus Unit.
■Mobile Suit Features
・General unit with cost of 650.
・This prototype unit is based on the Gundam Mk-II, and was developed by the Titans integrating technology
from old Zeon forces.
・Able to independently develop high-performance MS, the Titans successfully completed the Gundam Mk-II.
It featured human-like movement and structure with a movable, lightweight frame for exceptional mobility.
But as the resistance from the AEUG intensified, there was an urgent need to develop next-gen Gundam,
which led to integration of technologies such as the Psycommu from old Zeon forces.
・Pushing the limits of MS firepower, this prototype was equipped with a mega particle cannon,
and wired- launch, arm-mounted beam cannons for omni- directional attacks.
However, insufficient generator output and a Psycommu device that could not be scaled down in size
called for a much larger backpack, drastically increases the unit’s weight,
leading to a notable decrease in its mobility.
・Can be deployed both on the Ground and in Space.
