The True Heroine (Undertale) is a PvE map created by leo7668. If you are to dive into this map, just one warning: The map is NOT EASY. The creator spent 32 hours of hard work to make the Undyne the Undying Boss battle From Undertale in Minecraft. Thus, it’s pretty challenging for an average person. Indeed, you will have try again and again, and it is still possible to keep failing to beat the map. The game is turn-based and includes both Chinese and English text. This is made for singleplayer only. Some bugs are to be expected, so feel free to give feedback if you stumble on one!
