Take the lift up and you’ll reach an area full of Imperial forces and wookies fighting. Take the lift at the end down, then activate the Overcharge console at the end of the corridor to turn the lift on in the space where you crossed the pipe to reach the Purge Trooper earlier.

Once the room’s clear, activate the console to release the rest of the wookies. The main target though will be the troopers ahead. There’s also a second Climbable Wall to the left you can reach if you have the Jedi Leap and climb to find another Force Echo on the platform overhead. On the left is a Climbable Wall you can use to to a higher level with a Wall Run that will take you to an area with more Stormtroopers. From there, directly ahead of the door is a platform you can drop down to find a Force Echo from the body of a dead Wookie. You can either cut the crane rope to make a shortcut down below, or open the shortcut door to head back to where you were.
#ZEFFO ESCAPE THE UNDERGROUND JAIL UPGRADE#
On the other side is an upgrade bench to unlock a BD-1 upgrade Slice Security Droid. Outside the wookie prison you’ll find a shortcut door on the right you can open by grabbing the rope and swinging around. A cutscene will play out and then you’ll be able to get out the door at the end.

Interact with the console to release a security droid that you'll have to kill before you can actually release the wookies. Now go back to the room where the Purge Trooper was and through the other larger door to reach the wookie prisoners (this will also count as opening a shortcut although it won’t be relevant just yet).
