STAR WARS Jedi: Fallen Order

The crashed Venator is on Zeffo. In the Crash Site area where you are swimming and come upon a Jotaz that is fighting a number of Scazz, you start climbing on the wreckage. You need the double jump so you can reach the entrance on the right side of the area. Follow this area through to the end and you will find a room with 3 chests in it and a Jotaz fighting a couple scout troopers. When you step outside to collect the gold chest that contains a stim upgrade, you will unlock the achievement.

EDIT: So it seems that many people are having trouble getting this achievement. I didn’t do anything special when I got the achievement so I don’t know exactly why It isn’t unlocking for some but is for others. Only thing I could recommend would be to fully explore the ship 100%. I did this naturally which could have been why I got the achievement as soon as I reached the chest room.

So to get this you need to have at least visited The wookie planet twice and have double jump and the rebreather

At the venator crash site go up behind the Skazz in the circle arena. Climb the wall but instead of going left through the tunnel with the probe droids and towards the 2nd relic , double jump forward and climb ledges to go through the a huge engine exhaust.

You will then have to slide and avoid electrify and force push walls. You will end up inside the Venator. You need to work through this section to get the achievement (it’s a sizeable chunk with lots of stormtroopers and rope swings)

Your near the end when you have to force push a block & cut some power cables to proceed over a large gap. In the next room will be several boxes to slice and a force echo that called Jedi Funeral or burial.

Go through the opening to the right to see the area you need to use to access the second relic. The achievement will pop. Move left after it pops to get a bonus stim
