Shield Hardpoint

The concept of shielding a ship is conceivable, for it is an understandable and conceivable size. Planets are the size of hundreds of Starships combined, and so shielding them from attack is a far more ambitious cause. Similar to Weapon Hardpoints, Shield Hardpoints are powered by underground power lines connected to a Power Generator. A shield Hardpoint projects a spherical energy shield over a specific region of the planet.
By triangulating these devices and upgrading them, a powerful shield can be deployed to stop any incoming attacks from enemy ships. Upgraded Shield Hardpoints require more energy, and are able to project a stronger shield that can withstand more intense and unwavering attacks.
