Refining Alpha Ore into usable Alpha Matter is a time consuming process, during which you must defend your Alpha Base and it's Ore Reserves.

During a Raid, an enemy CMD Ship invades your Alpha Base with it's Fleet.

Enemy Players can initiate Raids on your Alpha Base at any time. Ensure your key Structs are Defended.

Any Alpha Ore in your inventory is vulnerable to Raiders. Refine Ore to protect it from Raids.

Your Ore Reserves are protected by the Planetary Shield. Raiders deplete the shield over time. When it reaches zero, the battle is lost and your Ore will be stolen.

Destroy the enemy CMD Ship to defeat the Raiders and force them to retreat.
