Minikit Guide - Chapter 10 - Lego Batman 2: DC Super Heroes
Police Boat (Minikit)
Required Characters: Cyborg, Lex Luthor
During the flying sequence, shoot all five flying Joker Boxes to get one mini-kit each.
Shooting down them boxes
After the checkpoint, destroy the golden part near the feet then reassemble it to become a missile turret. This will take out the roving chopper and award you with a mini-kit.
After pulling out the first fuel line at the back of the robot, three turrets will appear. Destroy all of them to get the mini-kit.
Destroy the hovering helicopter so you can assemble Batman's Power Suit. This will remove the cover of the magnetic plate on the robot's left ankle. Pull it then assemble the parts to become a mountable turret. Destroy all targets to get a minikit.
There's no perfect time for target practice
For the last two minikits, simply deconstruct the black parts on the robot's left leg and its groin.
