I help Emon take out the first wave of Razors, then head straight for the container transports while Emon and your turrets take out the Enkidu. Don't try to kill the transports, just cripple their engines to prevent them getting away.
Now slaughter as many Razors as possible. When Aeron is clear, take out the transports you crippled to make up the 25%. Don't forget to destroy the Venix.
When the Imps show up, pour everything into your engines and get the hell out of there.
