This is a port of the game INFRA (very great game), which means you need the game to see anything at all.

Why not just upload a content pack?

Uploading a content pack would be very impractical since it's way too much content. There would need to be six content packs (maybe even more).

Also, please don't download content. INFRA is a beautiful game, which took years to make by the devs. It took so long, they had to release it in parts. And if you want to play this map in its full extent, it's in the game itself. But then with puzzles. Please stop begging for content packs too.

I hope this discussion has been helpful to anyone who asks this question.

Don't judge a book by its cover.
