TerraFirmaCraft turns every bit of the original Minecraft's survival mode on its head, transforming it from a sandbox into a realistic simulator. TFC divides development into three eras - stone, bronze and iron, and now players will have to obey all the laws of physics during any of their activities - be it going to the mine or building.

For example, now, in order to cut down a tree, you need to find branches and stones, assemble an ax from them, and only then can you get several logs. To make planks from a log, you will need a saw, which cast made of metal. It must be extracted from nuggets in the ground. There are now 23 types of stone, earth and sand, 20 types of minerals, and 22 types of metals, including 10 alloys.

Please note, that you need Minecraft version 1.7.10 to work. The player does not need later versions - TerraFirmaCraft completely changes the entire game even without them.
