How to get the giga missile?

right I'm just making this so it doesn't fall to the back of the forums where people can't find it,

to get the giga missile, complete the story and all the order missions then:

story Mission 01
Destroy everything
the last recon unit is at the start of the map but wont spawn until the tunnel Cs
the Zodiac should replace the Police Ac
Also take less then 5k damage

story Mission 04
Kill the 2 Scavengers
and ignore all other units
then reach the city within 5mins ie boost like hell
another zodiac should spawn

story mission 06
destory all fuel base's
destroy LLL
ignore all other units
and kill every thing outside fathers base
and repeat since there's 2 Zodiacs on this mission
also take less then 10k in damage

when all this is done you should have the giga missile.
