Naval Energy Converter
The Naval Energy Converter converts energy into metal and can be built on the water. This makes it excellent to use on maps with limited or no land.
Build in smaller groups to prevent explosive chain reactions if destroyed.
Later in the game, you may have excess energy that’s going to waste. So consider building multiple converters to produce more metal. Converts 70 energy into 1.1 metal per second, and can be built by the Commander or other construction units.
When attacking an enemy base, aim for their converters to set off an explosive chain reaction and cause damage to other nearby structures.
