Supremacy

Here is a tip for 30,000 units of fuel. First, get rid of what little fuel you have by buying a couple of cargo cruisers, filling them up and putting them into orbit. The next stage is to buy a Solar Satellite, put it into orbit and then take it out again! Sounds strange but read on. Now go to the cargo control screen and press the scrap icon to decommission the satellite. You should now find that your fuel level has risen to the top of the screen and what's more, this can be done on every planet against every opponent.
