This guide will help you earn an S Rank score in the To Know Too Much story mission in Metal Gear Solid 5: The Phantom Pain, and includes a list of the mandatory and optional objectives available for this mission. Note that it is not necessary to complete all the objectives to earn an S Rank. You just need to accumulate a score of 130,000 or more, and earning the time bonus as well as some score multipliers will greatly increase your chances of getting an S Rank. 

Objectives 

  • Extract the CIA agent (Mandatory).
  • Extract the CIA agent before his discovery by the research team (Optional).
  • Extract four search team soldiers (Optional).
  • Extract the driver of the transport vehicle (Optional).
  • Extract two prisoners held in Shago Village and Lamar Khaate Palace (Optional).
  • Extract the Soviet soldier planning to execute the CIA agent (Optional).

Walkthrough 

For this mission, we will be skipping a lot of steps in order to quickly complete the mandatory objective. It is possible to earn an S Rank via the time bonus score alone, so speed is our goal with this mission. However, you may want to play through the mission first if you wish to do the optional objectives and secure new crew members for Mother Base. If you are ready to attempt an S Rank, then continue to follow along. 

After the helicopter drops you off at the landing zone, bring up your iDROID and place a custom waypoint about halfway between Da Shago Kallai, and Lamar Khaate Palace. This is where the CIA agent will be located. 

Now begin riding D-Horse straight toward your custom waypoint. There is an outpost that you may encounter along the way, and you can simply bypass the outpost by running past it. If the enemies at the outpost spot you, you can choose to take them out as long as you move quickly. However, this can take up time, and since speed is our goal with this mission it would be best for you just to avoid the outpost entirely.

As you approach the target, there will be some Walker Gears patrolling the open desert area. Be careful not to get spotted by these as you head toward the waypoint, as this can result in unneeded conflict.

Follow along the base of the rocky cliffside and locate the agent tied up on the ground. Approac and attach your Fulton Recovery Device to the target to extract him out of the area. Now, all you must do is exfiltrate out of the hot zone. Get back on D-Horse and start riding out into the desert, making sure not to get spotted by the Walker Gears. Once you have cleared the hot zone, the mission concludes. 

If you followed our instructions you should have completed this mission in about three minutes, and earned several other score bonuses, such as No Retries, No Kills, and No Traces. You will have also extracted the CIA agent before he is discovered, fulfilling one of the optional objectives. This grants you more than enough points to earn another quick and easy S Rank rating.
