S Rank Classified Intel Acquisition Guide

Note: Speed doesn’t matter here. All you need to do is ride the truck into the base, grab the tape, then ride the truck out. Don’t get spotted in the Admin building, and you’ll gain an additional “No Reflex” bonus.

  • At the start of the mission, you’ll appear in the back of a truck. Stay there, and ride it all the way to the Admin building.
  • Once the gate opens, jump out to the parking and unloading zone to the left of the road. Move fast; crawl under the pipes, then climb over the second set.
  • Use the Tranquilizer Gun on the patrolling guard to the right, near the parked jeep before climbing up the ladder and entering the central watch tower. Shoot the camera before going inside the tower, grab the tape, then return down the ladder to the parked truck.
  • Jump into the back of the truck, and wait. Eventually (after a few minutes or more) the driver will return. Just sit there and enjoy the ride out of the base. This isn’t the fastest way to win, but it’s guaranteed to earn S Rank, every time.

You forgot to mention that there is a camera in the tower pointed at the tape, congrats on making a walkthrough for the fastest way to fail.

Dont for get about the security camera in the tower.

If you take the camera out it works fine. Which is what I did.

Apologies to those having trouble! This correction was made earlier today to help those experiencing issues.

Because the camera is in a remote location, usually it won’t attract a guard’s attention to just shoot it. Normally, I wouldn’t recommend shooting out a camera for S-Rank but in this case there’s no other option. Hopefully Phantom Pain will bring back chaff grenades.

How about doing this on hard? Is that possible??

You can turn the power off to the admin building which disables the camera. The switch is opposite the jeep, in the fenced off area.
