"Essential for survival. Upgrade them and you'll get more Minerals."
The mine is a resource building that makes minerals. Minerals collected from the Mine can be used to:
- unlock units inside Training Camps, Factories, and Starports
- upgrade units in the Laboratory
- upgrade Turrets, Defense Bunkers and the Observatory
- buy new colonies, and
- travel to other peoples planets when attacking
- Mines generate Minerals over time. When their internal storage has reached the maximum capacity, they will stop generating minerals. The internal storage of mines increases as they are upgraded.
- If your mineral storage capacity is full, you will not be able to collect more Minerals. You can increase your capacity by building and upgrading Silos.
- A Star Base can store 9,000, no more no less, regardless of level.
- Mines will keep generating Minerals when destroyed.
- A level 10 mine will give up to 200,000 minerals when it is completely destroyed if the Mine was completely full before the attack.
- Mines take less time and coins to upgrade to a next level compared to a Compact House.
- Mines generate less experience and give out less war points than Compact Houses. Destroying a Mine cannot give more than 1 war point, even if the attacker's level is lower than the defenders as levels don't mind. A common tactic used by high level players attacking low level players is destroying one building and ending the battle. This gives you one war point no matter what.
- High level Mines have lots of health. Because of this, players will often line Mines outside their base along with Compact Houses, as to keep units with no target (no preference to attack defenses or anything) occupied tearing them down.
- Note: at level 2 the storage capacity is mentioned as 1k. However, calculating the 22 minerals per minute times 90 minutes makes 1,980 as capacity, so rounded 2k.
