Custom ship names
Use notepad to edit the .txt files that correspond to ships in the "\lucasarts\star wars empire at war\gamedata\data" directory. Examples of the files are "acclamator_assault_ship.txt", "alliance_assault_frigate.txt", "broadside_class_cruiser.txt", etc. Open these files with a text editor and add a name. The name will eventually be created in game once the location in the list is reached.
Galactic Conquest mode
Build a large space fleet and also have large ground fleet. Move around capturing planets. If playing as the Empire, try to attack Hoth because Mon Mothma is probably there. If playing as the Rebels, go for Coruscant.
Recommended Empire Space Fleet
You must build, to conquer space, buy as many Accumulator Assult Ships and Victory Star Destroyers as you can afford. You can also get some Imperial Star Destroyers and possibly a Interdictor Star Destroyer. Once you have your space forces, focus on your infantry. You may need to wait for more income because of all the space forces, but when you get enough, buy some of the first two things you can (for example, Storm Troopers or Scout Troopers), then a few tanks. This will also work for Galactic Conquest mode.
Recommended Rebel Space Fleet
Build at as many places as you can, X-Wings for space and Infantry Platoons or Plex Soldiers for land. Since X-Wings have such a high fire rate, they will kill enemies easily. When the space battle is over, take the ground with your forces. It may also help to have some T2-B Tank squadrons. With the Plex(s) as high defensive and your platoon(s) doing the rest, you should win quickly. This will also work for Galactic Conquest mode.
Various hints for Galactic Conquest mode as the Empire
Never leave a planet unguarded in space or on land. The Rebels can see every move you make, and can get past any blockade you may have set up with a small force. They will know at all times whether your planet is guarded or not and strike the moment you leave a planet venerable to attack on land or in space.
Try to keep each planet that is in your control well defended in space and land with at least one level 2 or 3 space station and a Victory Class Star Destroyer. On the ground, have a barracks and a light factory. If possible, also build a shield generator and/or turbolaser towers. However, build these last as the bigger your base is, the more turbolaser towers you get.
The Rebels tend to jump to hyperspace if there are transports in the battle. In space when the Rebels attack you and it looks like they have a large force against you and it appears hopeless, do not auto-resolve or give up. Usually their "massive fleet" is mostly made of transports. Just destroy some ships for about twenty seconds and they will jump to hyperspace; even if their space station is not destroyed and they have a larger force, they will flee.
Send Boba Fett to the planet you are planning to invade first and alone. He can not only kill enemy heroes, but he will also reveal the space craft orbiting the planet. Just move the pointer over the ship(s) surrounding the planet and the droid above your mini-map will show what and how many ships are in their fleet, unless they have Luke Skywalker. If they have Luke Skywalker, you will not know what ships they have; just how many different types of ship. If you keep Boba Fett at the planet you are invading, he will assist you in space and land battles.
To get the Death Star, put a hero that gives you space discounts on the planet you wish to build it on. Then, build a research lab and a level 5 space station with all the upgrades. The Death Star will cost 20,000 credits. The Rebels will be alerted of your new construction as it is being built. Both sides will have a timer on their screen showing how long it will be before construction is complete. Not counting space battles, it is about six minutes. Note: The Death Star moves extremely slowly; if you are combining the Death Star and another fleet, move the fleet to the Death Star and not the other way around. When you destroy a planet, it will become an asteroid field. It will not only produce less credits for the faction who controls it, but if you leave the "planet" with no spacecraft or space station, then it will become neutral and is free game for the Rebels to hide.
