Tips and Tricks:
Try and work your ships closer to the enemy while swinging sideways, so you can use all your guns at once.
Torpedoes seem powerful at first, since they hit anything in their path but as you get better at estimating the distance, the longer range and traverse of turrets becomes much more powerful.
Frigates, as the weakest ship class, aren't much use in a firefight. But if you put anti-aircraft weapons on them they are good at protecting other ships from air attack, and their high speed makes them good for collecting cards during campaign play.
