    You have to leave the SOCOM behind in order to get these cutscenes in the 1F duct

    I didnt take "socom", climbed into the F1 ventilation, listened to the guards' dialogue. But I didn't get the achievement!

    You need to have been detected at least once or part of the cutscene won't play and the achievement won't trigger

    was spotted and killed enemy and still did not get the intruder cutscene

    You also have to leave the SOCOM behind in order to get any cutscenes at all in the 1F duct. The grate where it happens is a little out of the way. You'll need to take a left at the fork. There's a ration in front of it if I recall correctly

    didnt pick up any weapons
    kirkisx 4 Jan 2022 03:34
    and also the 2nd floor cutscene doesnt happen either
    WilHiteWarrior 4 Jan 2022 03:39
    That's weird, if you have an alert recorded, it definitely should. I'm positive that's the trigger for it

    where is the 1F duct entry?
    WilHiteWarrior 22 Jul 2023 22:46
    It's in the West side of the area, there's a guard sleeping right in front of it
    waleedluiz 24 Dec 2023 17:59
    I did it. Now you must watch from the camera that is next to the enemy, then crouch down and enter the ventilation area

    Anyone who's struggling with this:

    Let me be very clear *You need to have triggered an alert*. If you haven't, they don't talk about an intruder and you won't get the right cutscene.

    Trigger an alert, kill a guy, get the ventilation duct with a guard sleeping in front of it.
    Turn left and just follow all the way to the end.
