Narbacular Drop is not a Torque game. If you download it, it doesn't have any of the folder structure that Blockland or other Torque-based games have. (using base/common/etc. folders)
Even if it was, they would have made it by editing the engine code which I do not have access to and even if I did I doubt that Badspot would add it to Blockland's main core for me and my one Add-On.
kipap, could you please edit or remove the huge page-stretching text from your post?
