• Hello @Sca7ha
    there was only one game world launched with this mode back in 2017 (link) and that's the reason this achievement exists. Currently we don't plan on launching any more game worlds with that mode as it is a bit more hardcore and time consuming compared to the normal worlds and the players interest was not so high. This decision however can be reevaluated if there is enough interest in another game world of that type from the community.

    Kind regards
