Adventure Level 1: Poe To The Rescue - Hangar Battle
Stave off First Order troops as you make your escape with Ackbar, bagging minikits as you go.
There are three grapple plugs you need to have a good old yank on to get this minikit. The first one is at the start on the left side of the corridor.
The second one is next to the terminal where you'll pick up your First Order disguise.
The final one is the corridor approaching the shootout on the right side. You'll know you're in the right place because you'll be taking hits as you get closer.
Minikit #2 - Free Play Mode
After the shootout, go around to the left to find some silver Lego pipes. Blow them up to get the minikit.
Head up the stairs to the left of the silver Lego pipes.
Destroy the crates in the corner to find a small access hatch.
You'll pop out on top of the catwalk above. Use the BB-8 platform to release the crates hanging from a crane.
Head back down and start smashing to find the minikit.
Minikit #4 - Free Play Mode
In the same room, go over to the right and hop up to the platform above.
Use the force on the crates up here so that you can climb them.
Climb over them and the minikit is yours.
When you jump on the lift to leave the area, you'll be taken past a gym. You need to shoot the two targets on your way past for the minikit.
