If you are demolished and have no recources to build anything and don't have any workers, go to the chat box and type "38". Your friends will then give you 500 resources which will be enough to make a worker.
Hope I Helped.

On the clone campaign, the bonus level is luke attempting to takeover corasant.

You start off with hardly and troops and a few space craft (which are next to useless because the level is littered with anti-aircraft turrets) the way to complete this level is as follows:- use Lukes conversion force abillity to turn enemy buildings into your own, convert prefab shelters to increase your population number,( to get resources use the cheats( forcecarbon forcefood forceore forcenova).

When ever your get some injured or dead units your can rebuild them at your converted troop center, an damaged vehicle, re-build it at your verhicle building place.

And so on, basicly you now have a endless army.

Have fun
