General information about the mission
Thirty-first mission of the Metal Gear Solid V is the last one completed during the first chapter of the campaign. According to the title of the mission, your main task during this mission is to defeat a huge combat mech called Sahelanthropus. The encounter itself will last for a couple of minutes and you should prepare for it beforehand (details can be found below), as the hull of the mech can take quite a lot of damage, and the enemy will have access to numerous powerful attacks.
- PRIMARY (1/1): Destroyed Sahelanthropus - You must deplete the energy bar of the enemy, which can be checked in the upper left corner of the screen.
- SECONDARY (1/2): Destroyed Sahelanthropus's head - Attack the head of the machine from the very beginning of the encounter, while using your rocket launcher for the best effect. It should be destroyed long before the end of the fight.
- SECONDARY (2/2): Successfully hit the floating boy with an attack- The floating boy appears near Sahelanthropus at the final moment of the encounter and when that happens, the game will enter a slow-motion state (even if you turned the Reflex Mode off). All you have to do now is to simply use your rifle, or rocket launcher to attack the boy, before he teleports into another place.
The mission can be played during any time of the day. If you've invested a lot of funds into your own Walker Gear, you can take it with you on this mission. Mount a rocket launcher, or a gatling gun on the D-Walker. If you haven't invested in your Walker Gear and you feel that it won't help you that much, you should take Quiet with you, while equipping her with the best available weapon.
The primary weapon of Big Boss should be a powerful assault rifle, and, especially, a rocket launcher. If you have access to a number of rocket launchers, you should take the one with the highest damage potential (precision of the weapon is the least of your concerns during this mission).
Note - Before you start the 31st mission, make sure that you have access to at least 100,000 GMP on your account, as you will have to call in the supply drop during the encounter numerous times, and those drops aren't free.
