Top Hat Toppler
Knock the silver hats off varius Chronopolis landmarks. You will need an anti-silver weapon to do it.
Start with the Statue of Liberty (Kang Edition).
It's often easiest to land on the hat itself to deploy your explosives. Other hats can be found on both panther statues in Wakanda,
the Sphinx of Egypt,
a floating sentinel statue in Hala,
a guardian statue at the palace entrance in Asgard,
and the giant skull over Hydra square.
Getting them all unlocks Kinpin's attack car.
