I NEED HELP!
I can't get past level 64, where you have to drive the Mech-Dog thing (don't know how it is called) and you have to kill those 7 helicopters of the rebells and than after you killed them, 5 tanks come out the base through that secret passage! Than I always get killed! What do I have to do? Do I have to get out and go through that passage in the base or do I first have to kill those tanks? PLEASE HELP!
