I like it but I'm a little confused.  If the shuttles are almost to the hyper point, and the ISD blows up is it over?  Also, if the Imps have to bail a huge ISD to get back to where ever the rest of the fleet is, hasn't the battle already lost.  I like it a lot, but I don't know if it's exactly cannon, seeing as how I doubt the crew views their own lives over the ISD.

Good point. A slight change then.

If the shuttles are almost to the hyperpoint, and the ISD is destroyed, they cannot respawn. So if the shuttles are destroyed after the ISD, the Imps can't spawn and they lose.

@Safe - I still prefer my idea, with the shuttle revision above.

So instead of getting the Star Destroyer specifically to Point B, you have to get that shuttle there. A lot more simple, yet much of the same effect.

But defending them is part of the challenge.

But the engines are in a big blind spot to the turrets. That may cause problems.

@jerk, considering that 32 angry rebels with torps are after 3 slow-moving shuttles, it will be very hard to escape. To destroy it completely - just keep pounding it with torps/lasers after the shields are down.

I like the idea of the two radar domes enabling the the Star Destroyer to scan the area around it. Gives the rebels an incentive to blast them, too.

I'm less enthusiastic about the battle continuing after the ship is destroyed, though. Surely taking out an Imperator Class should be sufficient to win a battle?

I also don't know about destroying engines, that somehow seems a bit too easy. But then again, that's probably what your shuttle idea is for .

Background: The ISD Destructor, with a damaged hyperdrive generator, was left behind at planet (insert name here) while the rest of the fleet moved on. With the damage repaired, it now prepares to leave the planet's gravity well to rejoin the rest of the fleet. But on the planet, factions sympathetic to the Rebellion have succeeded in getting out a coded message. As the Destructor heads to its hyper point, Rebel fighters and bombers hyper in, attempting to destroy the straggling ISD.

Forces:
Rebel: 6 B-Wings, 10 Y-Wings (2 seater), 6 X-Wings

Imperial: 1 ISD, 24 T/F, 12 T/I

Goal

The Imperials must move their ISD across the map to the hyper point (takes 20 mins), defending it. The Rebels must destroy or disable the ISD before it escapes. If the ISD's engines are disabled, the crew must evacuate and reach the hyper point in shuttles.

Classes

Pilot (both sides) - Unarmed
Crewman (Imperial) - repair tool (to repair turrets)

Notes

Ideally the ISD should move across the map automatically, but if that isn't possible the commander will have to set it. The ISD should have destroyable parts, firstly shields (but not shield generators), sensor domes (disables constant "UAV" scan around ISD), engines (becomes slower with each engine lost and eventually disabled), and hanagr turrets (auto-turrets defeinding hangar entrance).

If all the engines are destroyed, three shuttles spawn in the hangar. The Imperials then must get to the hyper point in these. They respawn, but slowly, and since the ISD isn't going anywhere the Rebels have more time to destroy it.
