Infiltrate the area around the estate | Mission 4 - Private Estate Splinter Cell: Blacklist Guide

Note - in this mission, the sticky noisemakers will again come in handy, for diverting dogs' attention. Additionally, it would be a good idea to take Trirotor with you, or the sleeping gas grenades because these gadgets can help Fisher stun the High-Value Target.

The enemy patrolling the vicinities of the starting point

Approach the edge of the cliff and use the hook to zip down the line in order to gain access to the estate's area. Right after you are done with this, hide behind the nearest wall, because one of the guards will come here from the tennis court, and he will start to comb through the area. Do not move and do not leave your cover before the enemy resumes on patrolling the area by going left.

Approach the right entrance to the garage and, for safety, destroy the lamp above it. Open the door and wait until the enemies in the garage finish their conversation. One of them will start patrolling the garage and the other should leave towards the square in front of the main entrance to the estate. Wait or the enemy from the garage to stop next to a car and approach, quickly, the Blacklist Laptop. Hack into the laptop to obtain 40thousand dollars.

The passage to the square in front of the villa

Quickly, stand behind the cover located the closest to the laptop and resume your actions as soon as the enemy from the garage changes positions again. After he does, go through the passage that leads to the abovementioned square in front of the villa. Keep vigilant here, because there is, apart from standard guards, a guard dog here.

Using the noise-emitting decoy is a good idea to divert the dog's attention

Unfortunately, the presence of the dog will considerably make your progression more difficult. As you can probably remember, you can't come too close to the dogs, or else they will move towards Fisher, or alarm the guards to your presence. Start moving to the right, dash from cover to cover, and try to keep as far away from the entrance to the villa as possible. You can additionally use the Sonar Pulse to your advantage, to monitor the current whereabouts of the dog. Still, it isn't necessary to succeed. It is also worthwhile to consider using one of the gadgets to divert the attention of the guards and the dog, like e.g. a Sticky Noisemaker.

Continue along your path and stop behind a cover every time you notice that the guard dog is dangerously close to Fisher. Eventually, you need to reach the side passage shown in the above screenshot, which is located to the right of the mansion's main entrance. Approach the door to the backroom and walk into the unguarded security room. Hook up to one of the computers here, which will result in a cutscene being initiated.

Additional tips for the Panther/Attack playing style: While attacking the enemies around the inaccessible main entrance to the villa, you should remember about the presence of the dog around, and do not let the animal reach Fisher.
