Game Show - Now you will be teleported into the game show. You will have to kill three waves of zombie before you can get any reward. Once you've done that you can choose one of three doors and get a reward out of it. There is a chance the reward will be the CRBR-S. If you want to reenter and try again you will have to progress 15 rounds from when you entered and if you go to the East Berlin Street there will be a building with a sigh that says Hasenbau and if its been long enough a bunny will be in the window which you have to shoot to go back. If the bunny isn't there look back in a round or two.
