First never kill a grunt with a assault rifle. (Believe me, I once did it and it is wrong!). Shoot grunts with DMRs and pistols, but not machine guns. Don't use power weapons either. That would be wrong. Shoot bigger enemies with those guns.
You need two players then go to forage then make a veical pres a in edit mode the make the other player get in it while you hold it then make the other player jump out then you got your golden spartan.
To lower weapon, hold X, A, and B and the down button on the D-pad and HOLD all of them at same time and your weapon will disappear.
First, you have to get a ghost on requiem in the rally point "a star to steer by" then after you killed all the covenant, keep going where your supposed to go but with a ghost then just melee the boosters off the ghost (only 2 hits will do the trick) then boost through the pole or console.
This video includes a step by step tutorial to perform a trick that allows you to Fly a Pelican in the Halo 4 Campaign mission, "Reclaimer". (This vehicle is not normally accessible outside of the mission "Shutdown").
