Gungan Creature Armor is a technology that is unique to the Gungans, and can be researched at the Mech Factory in Tech Level 4. It costs 700 Food and 350 Carbon, and gives all Mech Factory units +10% Hit Points.
This technology is less useful than Technicians, but at about the same price. Players should always research Technicians first, but if they can afford it, Gungan Creature Armor is a nice addition.
"This Tech Level 4 upgrade augments the resiliency of all Gungan Mech Factory units, thereby letting them absorb more damage."
