Coastal Highway/Walkthrough

This following is a Walkthrough for the mission, Coastal Highway.

Legendary
Recommended Skulls: Grunt Birthday, Cowbell

If you have completed the previous mission, you will know about the danger of the Huragok (the Engineer) being killed. Swap your SMG for Buck's Assault Rifle, Buck will come in handy later on in the mission. When you approach the Unggoy of the tower, this is where Cowbell and Grunt Birthday come in handy, aim for the Grunt's head, and kill him, and also, headshot the Grunts to the right with the Brutes, it will most likely kill the grunts beside them, and damage the Brutes. This is where Buck comes in handy, run up to the tower, and kill the grunts on the turret, since Buck will follow you, he will fire at the Brutes. He is useful due to his Invincibility. Play hit and run with the Brute Pack, and take cover behind cover. While Buck has them distracted, and possibly wounded, assassinate or finish off the Brutes. Now that the close-quarter combat is over, be careful about any enemies up until the Elevator/lift.

Once you reach the Elevator/lift, it gets harder. Get into the Warthog and wait for the Oliphant's shields to charge. With this section, you should consider avoiding any vehicles unless it is a spare Warthog which may be needed. For the next area, try to avoid the enemies up until the area where the drones will attack. While in that area, drive around the room in circles, avoiding the chance of getting shot and getting hijacked. Avoid enemies until you get to the Gauss Warthog, then it gets a little bit harder. Driving on to another area, get the Health Pack if needed. Once the door opens, reverse a bit so the Banshee will not have a chance at attacking you. Drive through the enemies, and do not approach the Wraith in the way. Avoid the Wraith and its gunner until the Oliphant opens the door.

Now avoid the enemies until you approach the Scorpion Tank, kill any enemy that follows you to the tank. Get in the tank immediately, now that the tank is here, destroy every single thing that poses as a threat, especially the Jump Pack Brutes, who can hijack you (Buck shoots in short control bursts, so he can't save you without taking a bit of damage.) Keep destroying everything up until the part with the Scarab, drive underneath the wall, to make sure it is 100% certain you won't be damaged along with the Oliphant. Drive on until you go down to the last underground areas. Get out of the tank, and jump over the barricade. Now is the hardest part. Make sure that when you reach the area, you are prepared. Also, make sure you still have your Magnum. When the Grunts arrive, make sure that you pickup a Fuel Rod Gun from one of the groups. Also, swap your magnum for a needler, and swap it in for the Magnum of Dare. She will use the Needler to a very good extent. Then, swap your Fuel Rod Gun for Buck's SMG. When the Jackals come, the Magnum will come in very handy at headshots. Watch out for Snipers running up the stairs in the middle of the carnage.

In the middle of the battle, a Hunter Pair will drop, and this is when Buck is very useful. The Fuel Rod Gun will stun the Hunter when it comes into contact with him. He will kill the Hunters quickly. Now, the Brutes will arrive, walk ontop of the balcony to the left, and use your SMG to kill the Brute Chieftain, his AI will allow him to get close to you, but he won't run upstairs even if he sees you. Use your SMG to cut his shields down. He will run for cover, check for Jump Pack Brutes attempting to jump behind you. If not, attack the Chieftain, who will run to cover. Once the Chieftain is dead, proceed to assist Buck and Dare, if you are in need of Health, run inside and grab a health pack. Stay near the Engineer for an Overshield, if you take cover often and fire short control bursts at the Brute's head, also, swap your SMG for a Mauler, and shoot at any Brute close enough to melee without a major risk of death. Eventually, you will prevail, now go to the right balcony, and you are safe from the Wraith's fire. When the Phantom arrives, the mission will end, and you can have the opportunity of seeing the secret cutscene, and will be one step closer to getting the Campaign finished on Legendary.
