Every metal mine becomes better at once.
Raises metal production by 2% per level on every colony.
Metal Processing compounds with every existing and future metal mine. Its return grows with colony count and mine levels.
Empire-wide metal scaling without spending another planetary field.
Improves metal mine output by {pct}% across all planets.
Research time depends on the Research Laboratory level, the Intergalactic Research Network and the universe speed.
Each level multiplies the previous cost by ×2, so each further level gets steadily more expensive the further you push it.
