Hvy Plating is a technology that can be researched at the War Center in Tech Level 4. It costs 250 Food and 250 Nova, and gives Mech Factory units +1 armor and +2 pierce armor. It's available for all civilizations except the Rebel Alliance. Medium Plating must be researched before it becomes available.

The final armor upgrade for the Mechs is a must-have technology for players that rely on Mechs.
