Hinterfall is a modpack for Minecraft that focuses on difficulty and survival, as well as NPC interaction. Food spoils, crops and animals take longer to grow, blocks have weight and slow you down, your health starts much lower but can be upgraded. Your items are not lost on death, but any extra health bonuses gained will be lost. Trade with NPCs from Millenaire, marry and raise children with villagers from Minecraft Comes Alive or command workers and soldiers from Ancient Warfare. Hunt wild animals from MoCreatures, survive the monsters from Lycanite's Mobs and even adventure into the Twilight Forest.
Unzip it and follow the directions on the ReadMe file. It is avaiable in .txt, .pdf and .docx (all the same directions). The Lite version is missing the texture packs and resource folders. If you don't want to use the edited Sphax textures, it lets you save some bandwidth.
On Minecraft main menu, choose Multiplayer. Click Add server.
I will eventually add more details to this site explaining the different mods, what they do, and how they affect the gameplay. If we keep playing that is.
