The Energy Converter converts energy into metal, and can be built by the Commander or other construction units.

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 metal per second.

When attacking an enemy base, aim for their converts to set off an explosive chain reaction and cause damage to other nearby structures.
