The Shield Generator is a 3x2 room unlocked at level 2. The Shield Generator is one of the earliest defense rooms unlocked and one of the most important defense rooms available. In combat, the Shield Generator will project a shield is basically a rechargeable health bar. The shield projected will absorb laser and ballistic weaponry, but will not absorb Missiles.


Battle Mechanics

The Shield Generator will always start off with a full shield in combat, even if it has no power. When the Shield Generator is destroyed, all shield hitpoints will drop to 0 immediately. Along with this, if a bullet that deals two shield damage hits a shield with one hitpoint, the shield will absorb all the damage. This is because leftover shield damage cannot be carried over to damage rooms.

In Combat

The Shield Generator's damage absorbing properties makes it a huge target for enemies. Since most starships also have a Shield Generator, many AI commands are set to target the Shield Generator. An important thing to note is that the Shield Generator cannot stop enemy boarders from reaching the player's ship. Thus, Armor and man the Shield Generator well.

When To Use

The Shield Generator is a necessary defense room for almost every type of starship, especially past level 10. There are not many reasons not to use the Shield Generator, and once the player utilizes a Shield Battery in conjunction with the generator, the shield becomes incredibly effective at absorbing damage.


Here is a good AI command to help save power. The AI will depower the Shield Generator once all weapons that can damage the shield are destroyed/missing. Shield Generators are also categorized as a "Shield Room" in AI coding.

Enemy Laser Room HP > 0% -> Set Maximum Power

Enemy Cannon Room HP > 0% -> Set Maximum Power

Enemy Craft Count > 0 -> Set Maximum Power

None -> Set Minimum Power
