In the first level of Hitman 4, Death of a Showman, there are many easter eggs to be found.

1. In the main courtyard before the main gate, look at the license plate of the car-- it says IO Interactive, the company that made the game.

2. The guards are wearing clothes that are fake brands-- the clothes comapny L.A is shown with the same writing, but is L.B.

3. When you place the gun in the soda crate, and are about to be searched, turn the camera so that you see the back of the guard frisking you--- His pants says "BUFU" FUBU backwards.

4. Finally, the guard boss, in the end of the level is called Scoop. That sound alot like Snoop ( Snoop Dogg) and he even looks like him.
