Quick Travel / Taxi
Three points is the taxi and quicktravel both Republic and Imperial side.
Find the Entrance
Go Up the Ramp
Just inside, there will be a little ramp bridge heading up.
Jump Over the Little Gap
Just up the bridge there will be a small gap you can jump over and into on your speeder.
From there you are trying to get onto a set of metal staircases at the end of the caged tunnel.
You can jump to the circular vent on the wall. I had better luck off my speeder.
Then you jump to the stairs. Don’t try and get a running jump off the circular vent, you’ll just slide off.
This set of jumps is hard and annoying, as if you fall, you’ll fall right into a patch of enemies.
Staricase
When you do make the jump, head up the narrow staircase.
From there, ignore all the lights and caged areas, just jump the big gap onto the shipping crates. Get a running jump and do it on your speeder.
From there, jump onto the crate with a pile of garbage on top – you’ll actually be able to see the datacron from here if you look up, but you’ll need to travel further to get to it.
Canopy
Jump from the crate to the canopy.
I think there’s more than one way to do this but next I jump onto the higher canopy.
Then I awkward fall down onto the floor of the edge of the building below the canopy.
From there you can sneak through a little crack behind an air duct.
Edge to Walkway
This is a hard jump at the end. It’s a very far, long jump. You’re trying to get back to the platform where the datacron is.
Back up, get a running start, and jump at the very end of the platform. If you don’t get a proper jump, you’ll land halfway up and have to start over.
Climb the Boxes
Once you’ve made that final jump, you can just climb and jump your way up the boxes to the datacron!
* The codexes Huttbreaker’s Rebellion and The Hutts Discover Mek-Sha are both from the Datacrons on Mek-Sha, but I’m not sure which is from which, as I have already collected all the datacrons and can not double-check them.
