Remember the old survival beta Minecraft 404 challenge? It has returned once more in 404 Challenge Enhanced Map with some new features, while also keeping a lot of the old beta mechanics! What is the 404 challenge? It was a challenge created by Neoxx that came into existence 5 years ago when world seeds first came out. It involved putting in 404 as the world seed for a survival world, gathering resources on the surface, and then when night time hit delving deep into a treacherous cave hidden below a patch of gravel. When in the cave you would try and survive for as long as possible while completing achievements, never returning to the surface ever again. You only had one life to work with – when you died it was game over. Using torches in the challenge is banned, meaning lighting up caves is a lot more trickier.
