How to Beat Borderline in Realism Difficulty

Realism Difficulty Tips
Shoot the Truck's Headlights Alternate Aiming Between the Two Men Fight Behind the Police Cars Use a Flashbang to Get Up the Stairs

Shoot the Truck's Headlights

After leaving the first house, you'll need to head down a path where you will encounter cartel members on 2 pickup trucks. The 1st pickup truck will just pass by you but the 2nd one will have members shooting at you.

The truck's headlights can diminish your line of sight and, while you can pre-aim and shoot above the truck, there's a chance you won't kill them. Shooting the lights out can significantly help your chances as you can get a better look at the cartel members.

Alternate Aiming Between the Two Men

In the second house you'll find 3 civilians, Alejandro will talk to the woman and follow her into one room leaving you with the other 2. During this time, make sure to ADS your pistol and aim at them to keep them at bay. Make sure to pay attention and alternate between them as they will slowly try to reach for a firearm.

During this time, Rodolfo interrogates them and they eventually give up Hassan's location. Alejandro will come out of the room to remove the shotgun on the wall and take the man's pistol and you can stop pointing your gun at them.

Fight Behind the Police Cars

After you get mistaken by the police as cartel members, an RPG will be fired from the house across the street. At this point, there will be cartel members heading your way. You will be able to reach for a pistol and kill one of the cartel members but there will be more to come.

Pickup the Kastov 762 in front of you and use the police cars as cover as you fight them. Wait behind the car and shoot them as they come.

Use a Flashbang to Get Up the Stairs

In the last house, there will be a Flashbang on the table. Pick this up and use it on the stairs as there will be a cartel member on the 2nd floor. This reduces any unnecessary peeking and allows you to shoot him as he gets disoriented.
