Fire linking (i.e. firing all weapons at the same time) can be an effective method of defeating enemies in space combat - especially if they are a couple of tiers below you. Especially effective is linked fire in heavy fighters that have more than two weapons, like the Kimogila fighter. The effects vary on the combination of weapons. One especially effective combination against shielded opponents is that of two heavy damage lasers and a powerful ion canon, which shreds through their shields.
Note, however, that linked fire drains a lot of energy, so it's a good idea to have a powerful capacitor and to set the capacitor status to override.
