Chapter 9: Destroy Starkiller Base - Rey's Escape
Add collectibles to the list of Rey's priorities on her way out of Starkiller Base, because we're grabbing them all.
At the start of the level, rather than building a ladder, assemble the bricks over to the left.
This will deactivate the barrier and you can pop in and pick up the minikit.
Minikit #2 - Free Play Mode
Build the ladder and scoot up to the next platform.
Use a character with the boost ability to reach the platform on the left.
Use the dark force to open the door here.
The minikit is inside.
Eventually you'll reach a stud wall.
Climb straight to the top to get the minikit.
