Cave Game Ultimate is a funky modpack with a long history. I have been "developing" this modpack since Minecraft 1.7.10 came out.
I was testing it with people around me and just having fun. My biggest inspirations were FTB Ultimate, Tekkit, Futurecraft and Attack Of The B-Team.

So what can you do?

Build fancy factories, transport infrastructure, defensive systems, and ultimate circuitry. Explore space and magnificent nature.

Progress to more advanced weapons. Make yourself a space station full of plants. Blow up the moon and then rebuild it on Mars (just an Idea).
