Description from the author of the map Hardmode time and good resources
Some may find Terraria easy to play, but I can assure you that it is not. You probably haven't played survival maps where you can show your abilities in extreme conditions.
Survival maps for Terraria. Are you tired of the original Terraria? Do you want something new? You can always download a survival map for Terraria and test your skills and knowledge of the game in a new environment. Typically, the goal of a survival map for Terraria is to survive in rather mock conditions, with many constraints and very limited resources. On such maps, you will no longer be able to freely walk around the world and calmly collect resources, which, if not in this place, then if you dig a mine behind that hill, then there will definitely be something there, and in general - the world is big, there are a lot of resources. Here you will have to fight for each unit of invaluable resources, since the resources on such maps are often strictly limited, and some especially important components for crafting may not be at all. So, survival maps for Terraria are a really serious test of all your skills in the game and a challenge for the most persistent and skillful players!
