Anyone else know about the fact that you can build trade federation units on the mission "Search for an underwater kingdom" .
Use darth maul and convert the workers that are the farmers in the north east area of the map.

Then if you want more units or sith lords use the cheat that gives you the resources then you can get up to tech level 4 thus making the level easier.

:koon:

There's a lot of times where you can cheat like a bastard and get units you're not supposed to have. Like Chewbacca 1. You can use the free resource code and create a base in the forest, but why bother? It's still cheating, and you're still playing the level in a way in which it wasn't designed to be played.
