All Collectibles in order as they appear. The characters used are just examples. Of course, you can use whatever character you like with the according abilities ;-) :
Part A: Freighter Battle
Open the door to the left with the translation ability, go through. Destroy everything and build a terminal to the left. Use the First Order ability on the terminal, fight the Rathtar and get the Minikit.
Open the container hatch with the dark force, build a power terminal for BB8, use it and reconstruct the Minikit
Use the hover ability to get onto the container.
Pull open a door in the corridor with grapple
Go through a hatch to the right. Use the force to pick up the key on the floor. Assemble the Minikit.
Part B: Freighter Chase
Run through the Minikit while in the chase.
Use the dark force on the cargo, then Ackbar to get the Minikit
(Ackbar can be unlocked at the "Poe to the Rescue" Mission)
Part C: Freighter Shutdown
Shoot 3 bats
Cut the vent with the lightsaber
Destroy the big box and use the dark force to get to the Minikit.
To the right, after you passed the toxic area, pull down the box with grapple and use the parts to play the color riddle. Go through the hatch to get the Minikit.
