A Cool Ship...
I've had this vision in my mind for the last few days. While working on one of my own games, this idea started to hit me about a ship for Star Control. Star Control ships are very simple, so they are always easy to describe.
There could be a ship somewhat like the Thraddash, but very different. This ship "has too much power to hold" and must ALWAYS be releasing it's massive amount generated power in some way or it will explode. So it is always discharging its massive overproduction of power through either moving, or shooting. The slower the ship is moving (if there is a reverse thrust that can adjust speed, if not ignore this part) the more brightly it begins to glow, and if it moves below top speed for too long it will eventually glow brighter and brighter until it explodes. When moving this ship ALWAYS leaves a fire/exhaust trail like the Thraddash did on afterburners. But this ship leaves this trail as normal movement... releasing all that extra energy it always must be releasing. When you fire... this fire/exhaust trail basically just changes direction. When you press the fire button thrust stops (but the ship still drifts in the direction it was going) and the fire/exhaust trail is now "shot forward" like a flame thrower as the ships weapon. The secondary ability releases all of the ships energy as an Expanding Sphere weapon (damage based on how much energy the ship had when it was activated)... a ring of fire emanates from the ship damaging ships and destroying any fighter/missiles/mines it contacts.
This ship is very different from the others, because you basically MUST move at top speed at all times. Any time the ship is moving less than it's top possible speed it starts to glow. It is also ALWAYS "firing a weapon" either with it's thrust or through "inverting it's thrust" as a weapon (but it does not thrust backwards when firing the weapon). This would be a pretty cool ship in Star Control.
