Underworld launch!

The second Rainworld plugin, Underworld, is up!..albeit without art at the moment.

The Gyre is a mess of tunnels, industrial vaults, and infrastructure beneath the ground, below the New Shenzen atmospheric processor. Space is at a premium; power rests in the hands of those who control the reactivated digging machines that built it in the first place. It's dangerous — but where isn't?

(I shouldn't do project pages at ridiculous AM; I initially failed to add community copies, which is fixed now.)
