Chapter 7: The Resistance - Resistance Hangar
The old gang are back together - for the most part.
Take the lift on the right to the upper platform.
Destroy the crate between the two screens and reassemble the parts into a socket for BB-8.
This will get you the parts to build your own minikit.
Back on the ground floor, head over to the right and use the terminal to set your comrades free.
The minikit is hiding inside the room.
Minikit #3 - Free Play Mode
Head right and into the next room.
Use the force on the jumbled picture at the back to get the minikit.
You need to put together three vehicles for this one. The parts for the first ship are in the room where you released the soldiers.
The parts for the second are in the room with Chewie's cookies.
Head to the room on the left side of the area to find the parts for the last vehicle and the minikit is yours.
Minikit #5 - Free Play Mode
Make your way to the upper left platform.
Go to the end of the walkway and switch to a character that can use agility bars to reach the minikit.
