The Last Suit You'll Ever Wear is a mission in LEGO City Undercover: The Chase Begins.
Walkthrough[]
Go up the stairs and then switch to the Robber costume. Open the hatch and then drop down. Open the costume container to get the Astronaut costume. Go over to the next room and stand on the astronaut icon. Blast through the roof (you have to stop the cursor in the meter properly or else you'll blow up) and then return to the guard and speak with him.
Stand on the next astronaut icon and blast off onto the next room. Smash the box up here and then use the smashed pieces to create a platform in which to push the other box here off of the roof. Do this and then it will smash into pieces. Throw the pieces together on the side of the building and then switch to the Construction Worker costume to activate the control panel that is attached to this building.
The lasers will then be removed. Jump into the dune buggy and stop in the next objective marker. Hop out of the buggy and switch to the Police Officer costume. Use the audio scanner to find the radio. Go dig it up out of the ground and return it to the guard. Now he will finally open the gate for you to continue deeper into Apollo Island.[1]
