Secrets and Easter eggs

Waving the Flag

While on the loading screen,move the left stick on the right to start the easter egg. You can play with it before the game starts

Hidden Lines

If you wait for a couple minutes without touching anything the character will mock the player and sometimes reference a character or a writer

Example:

Wonder woman: Now where did i park my Invisible Jet?

Zatanna: Wanna see a magic trick? Pull my finger

Wonder woman: Uhh this costume is designed by a man!

Another easter egg is when you find a hidden location the character will ask you to return back on the main road.

Bunny Island

You can find an island full of Bunnies this is a complete reference to the easter bunny hence the name "Easter Egg"
