Killing Revenants at Thargoid spire sites Mega Barnacles ?

[Patz]

I am struggling with the Thargoid Spire sabotage mission. I can enter the mega barnacle on foot without being noticed when I leave my SRV behind a rock in the outer valley, +/-550 metres from the mega barnacle center. Dropping the 2 materials goes well too.
But when I enter the barnacle with the SRV, I get detected by a Revenant, and 30 seconds later there are 4 of them and a banshee -> boom, back to orbit.

looked great, but I failed...

I have been trying to clear the site instead : I dealt with the banshee by luring it outside with the SRV, getting out on foot, and shooting its weak spots from under with a plasma executioner G3 + rocket launcher G1 while it shot my SRV (fine, I got 3 spares). I tried to kill the Revenants too, but one plasma or rocket shot was not enough. It gets red, calls its friends, and the next minute I am dead without being able to hide or kill a single one.

These bugs move too fast for plasma rifle/shotgun and rockets. Lasers didn't seem to hurt much. I only have shop G1-G3 weapons (no materials for on foot upgrade or engineering)

At that point, I'm tempted to fill my Krait with dumb missiles for a hit and run.

What strategy & weapons do you use to deal with those Revenants ?

You really need to upgrade your plasma weapons to be able to one-shot the revenants. It's so much easier than trying to deal with them once they're aggravated.

Also I'd look at this thread & the video within https://forums.frontier.co.uk/threads/raiding-mega-barnacles-u17-spoilers-duh.620634/

The hiding place under the barnacle works well once you work it out, and even allows you to 'dribble' the mats back to your hidden SRV without aggroing the banshees (I'll still typically need to clear out nearby revenants, and as Ned says being able to one-shot them helps a lot)

I actually tried to dribble the mat (I stumbled on that useful thread too), but I must be doing it wrong : it takes me 4-5 seconds to roll 1 m, so I gave up

edit :
ah, the cylinder shaped ones falling from the sack don't roll well, but the spheric ones are easy !

New strategy :
1. clear the revenants with dumb missiles
2. grab the cylinders materials with SRV and bring them back to the ship. Drop coral tree/root materials and leave them on the floor, as waypoints for the next trip.
3. come back in SRV and drop the red spheres with the energizer mini game. Leave them on the floor before the revenants come to investigate (do they respawn or did I miss them ?)
4. clear the revenants again with ship missiles
5. Try to grab the mats from the ship and fail while banshees and scouts make noise
6. come back in SRV, avoid banshees, grab the spheres, escape
