It's the level where you have to locate James Kidd and you're on that island with all the assassins on it.

I didn't keep track of how many check points I went through already >_> But it was a few. The part I am stuck at is a little...pond? There is an alligator visible in it and the water is surrounded by some manmade walls, it looks like.. But there are 4 assassins. It looks like 3 women and 1 guy. The guy is on some steps. 2 of the girls are standing in front of a tree and the third girl is walking back and forth between the 2 girls and the guy. I managed to knock out the walking girl and 1 of the tree girls by crouching and whistling in grass. But now I am stuck. If I go to the right, behind the tree, I get spotted by a 5th person with a gun above me somewhere...i am guessing a gun cuz the red attention circle has crosshairs in it.

If I go to the left, behind the guy, I get spotted by him and the remaining tree girl.

I tried using smoke bombs but I still get detected even when the smoke is dense.

Am I missing something? Because I have been stuck in this spot for two days now
