You can effortlessly obtain all five collectibles through the Story Mode in your first run of the mission.
However, you must know where to look because you can easily miss any of the Minikits.
So the only effort you must actually make is to check the Assault On Echo Base Minikits guide below to get all five collectibles faster.
Minikit #1: In A Small Tunnel To The Right
First, reach your army’s location at the start of the mission, and then turn right as you fly above the trenches.
You should now be able to spot the first Assault On Echo Base Minikit in a short tunnel.
Go through the tunnel without pressing the boost button, so you don’t hit anything and crash before getting the collectible.
Minikit #2: Shoot The Miniature Ice Castle Near The Trenches
Upon collecting the first Minikit, fly back toward the trenches and turn right to see something looking like a miniature ice castle.
Shoot at it to see the second collectible popping out.
Now, you have to fly your ship through the Assault On Echo Base Minikit #2 to collect it.
Minikit #3: Destroy Six Of The Smaller Vehicles
You can get the following Minikit by destroying six of the smaller vehicles that look like this:
You can do this in the first mission area before destroying the AT-STs.
There are plenty of the smaller targets around, but if you couldn’t destroy six of them in this first part of the mission, don’t worry; you can easily do it later because they will keep spawning.
When you destroy the sixth vehicle, you will automatically get Lego Star Wars Skywalker Saga Assault On Echo Base Minikit #3
Minikit #4: Destroy The Miniature Ice Castle On The Right Before Reaching The AT-AT
Continue with your current mission’s objective, and after you destroy the second wave of AT-STs, you will have to proceed forward to defeat the AT-ATs.
As you make your way toward the first AT-AT, you will see another miniature ice castle on the right.
Be careful not to miss it, so don’t press the boost button and pay attention to your right.
Once you spot the castle, destroy it and fly through Assault On Echo Base Minikit #4 to obtain it.
Minikit #5: On The Right Side Edge In A Tunnel
Upon collecting Minikit #4, proceed to the last area of the mission and, for now, ignore the AT-AT here.
Fly toward the right side edge of the area to find another small tunnel like the one from Minikit #1.
It looks the same, but it’s a different tunnel with a different collectible.
So carefully fly through it and collect Lego Star Wars Skywalker Saga Assault On Echo Base Minikit #5.
And those are all Assault On Echo Base Minikits in the video game developed by TT Games.
