The Game Formerly Known as Hidden Nazi Mode is a Z-machine interactive fiction game written with Inform 7 and is © 2010 by Victor Gijsbers. The game was released under the General Public License version 3.
In this children's game, you play as a child who wants to give tasty carrots to all the rabbits hiding in the neighbourhood. And that seems to be all it is.
But is there a hidden Nazi mode? The author says that stuff was removed. His published source code seems to confirm that. But then, why that title? Do you trust the author? Is his game really about rabbits or is it about finding out if it's truly kid-friendly or not?
This solution is by David Welbourn, and is based on Release 1 of the game.

So, is there a hidden Nazi mode? Yes. Yes, there is. The provided source code is a sanitized version of the full code of the game.
> restart
What is your first name? > NAME
Next to the busy street
To learn this command, I went to the trouble of using BABEL to extract the Z8 story file from its blorb, then used TXD to disassemble the Z8, and then I searched the "Action routine for" sections until I found this suspicious-looking command. (Later, I noticed that the IFWiki page for the game had already been updated with this spoiler.)
CAUTION: Once you're in Nazi mode, there's no command to turn it off. You'll have to restart if you want the bunny rabbits back.
> join the ss.
You are now in Nazi mode, and your mission is to shoot your enemies. All the rabbits have been replaced with people, and your carrots have been replaced with a rifle.
> x me. i. x gewehr. sing.
> e. n.
In the Grocery
> x man. kill man.
The game abruptly ends instead of shooting him. The author says a few final words.

As far as I know, this message in the disassembled code is only visible that way and is never displayed by the game, even in Hidden Nazi Mode:
Hey, I see you! YOU ARE REVERSE-ENGINEERING this PROPRIETARY piece of software! Think you are pretty clever, huh? Well, believe me--you are not half as clever as our lawyers, and they are going to BUST YOUR ASS for violating the DIGITAL MILLENNIUM COPYRIGHT ACT, or whatever law in your country allows big corporations to sue people like you! THIS CODE IS MY PROPERTY, and you better STAY OUT of it, PUNK!
