Mission 28: Code Talker

- This is a fairly lengthy, story driven mission in which you should bring Quiet for the first portion and D-Dog for the second. Also bring your most powerful (suppressed) sniper rifle, and some sleeping gas grenades/mines.The first part consists of moving to the valley until you encounter four sniper Skulls. Although you can escape from the battle, it is advisable to at least kill three Skulls. This indeed allows you to extract Code Talker in a much less tedious way than you would should you kill all four (or let all four live). Middle ground it is; leave only one of them alive.

THE SKULLS

- How to approach these sniper Skulls? Quiet can provide excellent backup, although the Skulls can take her out if you push it too hard.

- Be sure to mark all four Skulls. Quiet can help you with this.

- I[Subsistence]'s important to stay out of sight at all times. Sneak and crawl behind rocks and preferably only fire if you have a clear headshot. You can use Pentazemin for a steady hand.

- When you hit a Skull, they'll move to a different position. This usually means you lose sight of that Skull, so look for visual cues, mainly the laser sight of their sniper rifle to relocate them.

- If one of the Skulls warps to your location, you can counterattack their close range melee attack.

- After dealing with the Skulls, bring in D-Dog and continue to make your way through the valley until you reach a mansion. There are various guards here, so use sleeping gas grenades and your tranquilizer pistol (or sniper rifle, if you have a suppressor) and start taking them out systematically.

- Your goal is to reach the back of the mansion. Enter through the door, move to the left and head down the stairs. Code Talker can be found at the end of this hall.

- After the scene, carry Code Talker all the way back the way you came. This is easier said than done, but not all too hard if you've chosen to leave only one of the Skulls alive. Normally the valley would be swamping with regular soldiers, but now they will all have been turned into zombie/puppet soldiers, which are by far the easier targets (and it is much simpler to avoid them altogether). The remaining Skull can just be avoided. If you manage to extract Code Talker without him taking any damage whatsoever, you automatically complete an optional mission objective.

- One of the other optional mission objectives (extract a Skull) is impossible on a first playthrough. Wait until you have the right Fulton upgrade.

- The last optional mission objective - extract the armored vehicle - requires you to move to the west of the mansion and look for it at the main road. You may have to neutralize any nearby enemies first.

- [Subsistence]-Rank Tips: Speed and (total) Stealth are, as usualy, key. Leave one Skull alive, and rush towards the chopper with Code Talker. Be sure to not be seen by any guards, and only tranquilize your targets.
