I'm one trophy away from getting platinum. All I need is the "Hard as Nails" trophy which can be obtained by beating all campaign missions (not including what-if missions). I've beaten all of the Resistance missions and 4 out of 6 for Security. Why 4 out of 6? Because I can't beat Shipyard. Even with friends it is seemingly impossible. I've managed to repair the crane a few times but then I fail with respect to hacking the missile. If anyone is out there I'd appreciate it if you would be able to help me beat this damn mission. My PSN is Spiral725. Thanks.
