Shields, ray guns and targeting computers.
Ever since I started playing SE I had this idea that I thought was interesting. I realized that battleships and large combat craft were at a disadvantage in the game because they are large targets and have few strategic advantages, which is a shame because, in every science fiction that has featured them, capital ships are an invaluable asset.
To remedy this, I came up with the idea of a Shield block. The shield block would make a ship invulnerable to all weapons at the price of the block's large size (5x5x5) and massive energy drain. The Shield block would be set to a certain frequency that would need to be decrypted by a different kind of block on an enemy cruiser.
The targeting computer would link directly to an antenna on a cruiser or battleship to search for enemy shield frequencies to deactivate the shields. The use of the targeting computer would create a massive energy drain but it would improve the accuracy of the turrets onboard. The targeting computer would have the option to "pulse" once it has honed in on a shield to deactivate it for a short time. To completely destroy the shield block, you would need the last block: the ray gun.
The ray gun (please suggest a better name) would be a turret act in tandem with the targeting computer and deal no physical damage, but once the targeting computer deactivates an enemy shield; a single shot towards the enemy ship will cause the shield generator to explode as well as causing random blocks on the ship to turn off completely.
