Build Ships Without Losing Energy:

If you need more fleets, but your systems read low or slots are out of available energy, change the location of the construction to a neutral system (it can be inhabited or uninhabited). The ship will still have a cost in maintenance and refined points, but it will save energy.

While in a battle, highlight any ship and hit Tab to get first person view point of that ship.

How to keep Captured Characters From Escaping:

When capturing enemies, it's always best to gang up on them with several good "name" characters, like Han, Luke, Madine, etc. Use a decoy. Have some (usually 2-3) Infiltrators or Death Commandos standing by at your return base. When you're successful, transfer the prisoner with the Infiltrators/Commandos to the FURTHEST POSSIBLE BASE from where you are. Try picking a base with a big allotment of troop training facilities. Once the troops arrive (R2 will announce because the prisoner is a "character"), send them to another base you've set up on the opposite side of the galaxy. Try shooting for a base with similar qualities at least 100 days away. If you nab the Emperor or Vader, it might be worth your while to put at least 12 Infiltrators with them.

Here's the trick:

unless the destination is taken over by the enemy, the secret mission is out of touch until it reaches it's destination. With enough troops and SpecOps at the other end, and with an immediate launch back to where they just came from, they'll never escape. I've played games where I've had 24 of the enemy's 30 characters "in transit" and unable to escape (with 5 dead and only Vader eluding capture).

Easy Fighter Killing:

This is for places like Coruscant where there are a lot of fighters. Get a fleet really close to the enemy system. This fleet should have 2 Corellian Corvettes and 1 Escort Frigate (Nebulon B's if you have them) but NO FIGHTERS.

Jump into the enemy system and unpause. When the enemy fighters start moving, pause and jump into hyperspace. The fighters will have reached you and exchanged shots. If you were quick enough they won't damage you but their squad size will be reduced. Repeat as needed.

Fast start for the rebels:

The empire allways begins with a planet that supports the rebellion, but is subjugated by a big garrison of ground troops. if you gather a large fleet with several fighter squadrons and put a commander with high leadership and combat (Han Solo or Wedge Antilles) you can easily blockade the planet. Then promote the commander to admiral status. Then bombard the imperial miltary units. Once you have destroyed all imperial units the planet automatically joins the rebellion. Liberating the planet will cause the rebellions popularity to skyrocket often causing several neutral systems to join and imperial systems to uprise. Then you can liberate the imperial system which are pro rebels and soon you control the whole sector. I once conquered an entire sector (sluissi) by day 34 using 2 corvette`s, and a fleet carrier carrying 4 Y-wing`s & 2 X-wing`s, commanded by Han Solo. P.S. You can prepare for planetary shields by having a good spy, like Chewbacca
tagging along.

Take a planet:

First target an enemy system and bulid 8 either bulwark battlecruisers or 8 super star deystroyers and commence a planetary bombardment (which will deystroy all their defenses) then invade the system with 12 or more regiments (this should elimanate all chances of a uprising) then continue to run diplomacy missions until the planet is loyal to you.

Take a planet...the easy way:

Chose a planet you wish to take over. Invade with a fleet large enough to hold the system. Once you have a blockade of the system bring a strong force character (jedi Luke or vader) onto one of the ships. Send them to take out whatever generals they have controlling ground forces. Once thats done you can send them to take out the shields and defenses as many times as necessary with very little risk to themselves. After defenses are down you can incite uprising until they turn to your side without losing any ground forces or wasting time with diplomacy
