First take out the wave of Rzr/F fighters (about 4 ships), then take out the PES Enkidu
followed by the remaining RzR/F fighters (about 6 remaining). Watch out if you are takingon the PES. If you can trail the PES it doesn't take much effort, but take care if you are coming head-on with it. It can do some serious damage if you don't watch out!
best thing to do is put all Shield energy to engines, head towards him at a 45 degreee angle, and as he passes you cut to 1/3 throttle and get behind him, or in my terms shields to -2, 45 degree angle of attack, and cut the throtle to get on his 6 as he passes
Take out some extra cargo ships and containers to get bonus points or to reach your 25% mark if you haven't taken out all the fighters.
Make sure you destroy the CORT Venix before you leave (MAKE SURE IT IS THE LAST THING YOU DO!!!!)
