The Shield Generator inside of the capital ship is a vital piece of the cruiser. Without its shields, the ship would be easily destroyed. It is responsible for protecting the internal parts of the ship as well as exterior. This is easily destroyed by Marines (5 Missiles) or by Pilots (6 Time Bombs). This room has one turret in it (in Campaign mode), and is fairly defended. It can be repaired or rebuilt, but takes quite a while to do either, and the AIs do nothing to repair the generator, which makes teamwork with other players essential to repair the generator in time to have an effect on the battle.
