How do you beat Lego mars mission level 9 d-day?

This is what I did. Put all of your drones in the transport except 1. Then put 1 sabotuer in the transport. Send the transport on the other side of the defenses, in the middle of the T intersection. Put half of your troops on one side and the other half on the other side. Let both teams kill the astro on each side, the let them destroy the trikes on both sides. Make sure the the sabotuer does not die and let him go inside the breeding pit. Back at base, make sure one of your guys gets the money box next to the generator. Then make 1 sabotuer, and about 2-3 strike attacks. Let both teams attack the guns on both sides, then let the strike attack kill the astro with the jetpack. Then destroy the generator, and soon after that, send the sabotuer inside the sonar station.
