“Hitman 4: Blood Money“, Easter egg (zombie) on Mission 7 - Death on the Mississippi

When you start out run to the left and up the stairs on the right. You should see a sailor guard come out of the left door - kill him. Drag the body into the room he came from and dispose of his by throwing him over the right rail. Now get back to the starting point. You should now see a sailor guard followed by one of the Gator Gang members. Go behind him, get out a firearm and use him as a human shield, drag the Gator guy up the stairs and into the room where you disposed of the other body but instead throw him over the left rail. Everyone on the ship will now be a zombie. They will try to kill you wherever you go so you better have some weapons on you.
