Tip of the spear
tips for taking out the 2 hunters and the enemies defending the last AA gun
- look around ammo crates nearby, one nearby the gun, one nearby the cliff edge (near the wraith) and one near the bridge
- 2 energy pistols located in the crate near the gun, to the right of the 1st hunter
- plasma launcher located in one of the creates near the cliff edge, along with some more energy pistols. (also another plasma launcher located before you enter the area, next to a revenant and 2 ghosts when exiting the mining facility.)
- grenade launcher located near the wrecked falcon near the far back of the area
tips for the 10 EMP
the grenade launcher you get at the very start wasn't help for me, i used the energy pistol on the ultras and elites, using the DMR/NR for the headshot.
as said above, theres a few ammo crates with energy pistols in, and grunts carrying them, so keep picking them up and restocking.
tips for headshots
check for ammo crates with needler rifle
- right as you enter the mining facility, theres a few stairs w/ a bunch of grunts, nearby is an ammo crate w/ 3 needler rifles in it, if needed track back and re stock your ammo.
tips for 25k score
i had 4 gold skulls on, tough luck, catch, famine and thunderstorm, this should easily get you the 25k, i got 61k doing this.
tips for no vehicle kills
dont use the hog when a marine is in the hog turret, if he gets a kill it counts as you getting it too (this happened to me, i didnt know)
also, i used a ghost a few times (when low on ammo), i used it just to take the ultras shield down, then popped them w/ a headshot
