Steamcraft 2 is the second iteration of Proloe’s Steamcraft mod. Other than the name, and a few of the original Steamcraft features/ideas, the mod has an entirely new take on all things steampunk. Its aim is to extend Minecraft by adding post-apocalyptic, retro-futuristic blocks/items for your (and our) enjoyment. With everything from Rayguns and Lightning Rods to Coffee and Smog, this mod is inteded to immerse you in a Victorian-era world.
