Quake 2: The Reckoning Easter Egg - Rocketman

On the level 'Indusrial Facility', go to the exit that leads to the refinery. Rocketjump (see the egg 'you crazy rocketjumpers') above the door, and then again onto the ledge that should be right next to you. If you look around you will see an invincibility farther down the ledge. When you get close enough to it, it will disappear and the message 'No prize for you, rocketman' will appear.
