The Auto-Tracking System (or ATS) costs 5000 RU to build, and it allows the Ion-Bolt Gun, Fusion Blaster, and Hellbore Cannon shots to home in on the enemy ship. More of these on the ship means better homing capabilities, but any more than three will do no good. Like the weapons, the ATS also draws power from the main battery (one battery unit per ATS module per shot). The technology for the ATS must be bought from the Melnorme.
One useful trick is to mount Hellbore Cannons in the forward and spread positions and carry three Auto-Tracking modules - fired at the right distance, all three shots will hit the target, inflicting an incredible amount of damage, enough to kill many ships in one shot.
