BrassBlocks is the unofficial steampunk Minecraft server of the Brass Goggles forum.
The server is running a custom Technic pack, based on the Direwolf20 FTB pack, once upon a time. For a quick and easy guide to installing there’s a section below.
As an aside note our pack adds a lot of stuff, but you don’t have to use any of it! Much of the stuff, like marble and red cobblestone are purely decorative and you can play regular Minecraft without a problem! Don’t be disheartened! the Brass Blocks pack mostly adds tiers of advancement beyond Diamond, and you need to play through basic Minecraft to get into the ladder to start the extra stuff.
Paste http://www.technicpack.net/api/modpack/brassblocks into the 'Add Pack' field of the Technic Launcher and simply click Play.
