I can't seem to beat the first level of the Toughlevels plug.
The first level seems to be designed so that if you wait until the most of the ships have warped in, you will be able to attack the Audemedon HVDs from behind. I have also tried moving to the planet quickly in the beginning, but that doesn't seem to work too well...
By waiting and attacking behind, I can knock out all but the Salrillians.
All of the built-in, single player levels are easy, with the possible exception of the one where you have to rescue the Elejeetian liner, and are attacked by the Salrilian carrier.
Anyway, TIA.
