Mod for Factorio - Space-Age: This mod makes it possible to unlock the Cliff Explosives on Nauvis and not have to go into space first.
The cliff explosives are unlocked in the same way as in the base game. You no longer have to leave Nauvis to research, produce and use cliff explosives.

For those who find the new unlock of cliff explosives in Factorio: Space Age annoying or who want to build your base on Nauvis safely and to your liking without being hindered by cliffs before you leave the planet, I have created this mod.
