If you were wondering how to get to the prison island in LEGO City: Undercover, then you have come to right place!
Reach the prison island
To start the next mission, go to the back of the police station and smash the garbage can, then rebuild it and go through the gate. You will meet a captain, who will commission you to build a ferry boat for him. This is no simple task - you need 15 000 blocks in order to complete it. However, in this moment, you scanner will be improved.
You can activate it in any place to find Super Bricks in your vicinity, which will allow you to quickly find the blocks you need. Destroying large objects also allows you to collect small quantities of the "raw material" you require. When you deal with this task (the fastest way is to collect the large Super Brick on the top of the radio tower, as shown in the picture above), go back to the captain and build the ferry boat. To continue the journey to the island, use the ticket machine by the boat.
In this mission you are no longer receiving any hints. First destroy the brown chest by the fence, move it to the green block, and rebuild it. Destroy another block, to find the place where you will begin a search that will lead you to a pile of garbage. Take the key from there and open the lock by the door. You can use the terminal inside to open the gate to the next area.
As you can see, after the completion of the second chapter can now move in an arcade style along blue and white areas. Turn left behind the gate, rebuild the garbage can and jump up, between the plates, by using the jump button, and press it quickly on the inclined surfaces. Then, follow the fence, and go along the edge of the wall.
Go along the wall and get through the fence near the guard tower. Your goal is located on the pitch. However, the entrance is guarded by two inmates, who want you to retrieve the ball for them. Make your way up the wall and then behind the fence, build a catapult there, in order to get onto the closed field, where the ball is located.
You have to beat all of the opponents and then cuff them. From now on you can also utilize a guard in fights, which will allow you to protect from attacks. You do not have much time to cuff a downed opponent, so make sure you do it instantly. At the end grab the ball and take it to the inmates by the pitch, and they will let you inside where you can talk with the other prisoner. After the conversation, go through the door to the prison blocks.
