Splinter Cell Blacklist Grims 4th Echelon Missions represent the first set of secondary missions that can be played in single player or in coop.
They can be started by speaking with Anna Grímsdóttir or from the SMI menu. There are three Grims 4E missions and each of them features three objectives, which consist of planting taps or recovering documents.
No checkpoints are available during the mission, so it has to be done in one go. Complete all three for an achievement.
Also, a distinct characteristic about Grims missions is that they must be completed undetected, otherwise the mission will fail. Bonus points are awarded if the enemies are not disturbed, hence it is recommended to use the stealthiest suit (the final level is unlocked if you complete all of Anna’s missions).
Each mission features three Splinter Cell Blacklist collectibles, but not all of them are easy to get. Therefore you should use the information found in the following guide to collect them without alerting the guards or failing the mission.

Dead Drop Flash Drive
Depending on how you play the mission, you can get other collectibles first. But if you go in the showroom where objective A is you can collect the Dead Drop flash drive.
Past the cannon is an entrance to an elevator shaft (near the coop route). Get inside and climb up to get the Dead Drop.

Blacklist Laptop
Get inside the next area where you can find an old plane. Be aware of the dog and when youre done with him use the entrance beneath the staircase.
Theres another enemy in here but it shouldnt be a problem. Head inside the room to your right (objective B is on your left) and dodge the lasers to reach the Blacklist Laptop thats on the desk. You can deactivate the lasers on your way out.

High Value Target
Head for objective C thats on top of the roof. Theres a sniper that covers the roof, and he is the High Value Target youre looking for.
Find a way to go behind his position or he will spot you immediately.

Dead Drop Flash Drive
Depending on how you play, you can get the HVT when the mission begins or you can wait until the end, when you make your way back to extraction.
The Splinter Cell Blacklist Dead Drop is in the attic of the building with objective A. Get to the objective and check for a hole in the ceiling right next to it.

Blacklist Laptop
Get past the location of objective B to find another building, but watch for the sniper. Infiltrate on the left side and be careful not to alert the two armored enemies.
The Blacklist Laptop can be found in a room downstairs (below the room with objective C), but its protected by lasers. You can use the table to dodge the lasers or if you want to be sure you can circle around the building and enter using the windows.

High Value Target
You can get the High Value Target when you start the mission if you go on the right side and climb between some cliffs/rocks, but watch for the minefield.
Alternatively you can capture him after you get the last objective and you need to return. Instead of using the same way to get back, climb on the roof and use the zipline to get between the cliffs, right next to the HVT.

Hackers’ Den Mission Description
INFILTRATE THE HACKER DEN AND TAP THEIR COMMO WITHOUT RAISING THE ALARM

Blacklist Laptop
The order in which you acquire the collectibles may be different depending on the objective you want to complete first. Get inside the building on your right, past the lasers, and complete objective C. Then drop down to ground level and turn around.
The Splinter Cell Blacklist Laptop is right in front of you, inside a small basement area. Use the walls to your advantage if you dont want to trigger the lasers around the laptop.

High Value Target
Head towards objective A. Hack the system and then get through the hole in the wall to find the HVT in the next room.
There are two more enemies in this area, so knock them out before securing the High Value Target.

Dead Drop Flash Drive
The sniper is inside a tower that can be climbed from the courtyard.
However, the Dead Drop collectible is in a similar tower, right next to this one. Climb that one to find the collectible at the top.
