Halo: Spartan Assault

In this mission, you will spawn alongside two Wolverine mobile tanks and be required to escort them to the furthest side of the cliff towards the North East of the map. This achievement is very easy, as the Covenant forces do no do that much damage to the Wolverines with their standard Plasma Repeaters and Plasma Pistols.

The only enemies in this mission are Grunts and Elites. From the start, simply run forward, and start taking out all the Covenant forces that stand in your way. Be sure to either occupy the Shade Turrets and blow them up, so that the enemy cannot use them.

If the Wolverines take any type of damage during the course of this mission, that’s okay, it won’t effect the achievement. The only way to void this achievement is if either one of the, of both, completely blow up. Just be sure to backtrack behind the tanks when necessary, because once you reach the middle section of the cliff, some enemies will begin spawning behind you. Also, do not step right in front of the tanks as they might run you over!

In the third mission of the game you will need to escort two Wolverine mobile artillery vehicles to a designated location. This task is actually quite easy, as long as you clear the area ahead of the Wolverines and then backtrack to cover them.

What I did was rush from the start point until you reach an area that has a fork, with one path going cliffside on the left and a wide open area on the right. Tons of enemies will come from both sides here, so make sure you kill all of them before you progress. Keep a medium pace up the right path once you're clear and you'll soon start hearing that the Wolverines are under fire. If you don't have the Tunderstorm skull equipped (I used Hollow and famine) they will be fine for the time being. Keep clearing until you reach a dead end with some grenades and ammo, then backtrack to the rear of the farthest Wolverine, as he will have a number of enemies following him at this point. Once the Wolverines have reached the destination, there will be one last dropship near the edge of the cliff at the farthest point in the map. After clearing the ship's enemies, you'll be done.

If you're having any trouble, you could try using the sniper rifle, which costs 1,000 XP for this mission alone. It will clear entire lines of enemies in one shot, so be sure to line up your targets to maximize your points and ammo useage.
