N-Fusion a mis en ligne les outils de développement nécessaires pour créer des missions solo et des cartes multiplayers sur Deadly Dozen 2 :

These editing tools and documents allow you to create and edit single player missions as well as multiplayer maps for all game modes. To install just unzip into your game directory (nWorld.exe has to be in the same directory as ddozen2.exe). As was the case with DD1, these tools are very unsupported.
