There are three different editions of The Underworld:

Public Builds (Demo)

Nixie’s Story is a free, hour long adventure with a complete, self-contained story arc.  Explore Mulberry, get transformed, discover The Underworld, conquer The Swamp dungeon, become a Dragon Queen, lay some eggs, and raid the Dragon Temple.

(Story-wise, this corresponds to the first three chapters of the full game.)

This is a fully stand-alone adventure inside The Underworld.

Private Builds contain exclusive content that will never be available in the public build.  Private builds include access to:

  • Additional story chapters available only in the full game (for example, Chapter 4: Cowgirl Farm), including their own new transformations, dungeons, and enemies.
  • Debug Character Customization Rooms – Instantly level up your character, immediately get plot objects (ie dragon collar, sewer pass, etc), use character transformation items to customize character
  • Debug Skip – Skip intro text and start with a character who has no tf items (blank slate character)
  • Debug Teleport – Instantly teleport to the start of any dungeon
  • Monster Mods – Create your own monsters to fight

Private Build access is a one-time fee of $14.95 USD: Purchase Now and you will continue to receive new private build updates as they are released.  We currently support payment via:

  • Credit & Debit Cards (American Express, Carte Blanche, Diner’s Club, Discover, Eurocard, JCB, MasterCard, Novus (All variations), Optima, Visa, Switch/Solo)
  • paysafecard
  • Wire Transfer in Euros
  • Mail/FAX
  • Bitcoin
  • Paypal (via Patreon only)

Please note that credit card transaction processing is securely performed by an external online store, BMT Micro, a trusted name in e-commerce since 1992.  SkyCorp will not receive or have access to your credit card number.  The charge will appear on your credit card as:  “INFO.BMTMICRO.COM 910-792-9100 NC”

If you don’t have a credit card and live in the USA, you can buy prepaid mastercard/visa gift cards from many retail shops (Target, Walmart, gas stations, etc).  These can be bought with cash and work online like a debit card (check instructions included with the card — you may have to go to the card’s website to enable online purchases).  For customers around the world without a credit card, Paysafecard works similarly.

Private WIP Builds

For the extra adventurous, private WIP builds are available to high tier backers on Patreon who are comfortable experiencing content that is not yet complete.

These are work-in-progress builds made in between private builds.  For instance, they might show a chapter with only the first part of the chapter content.  Saving may or may not be disabled for these builds, and they are not as well tested generally.  They will contain sections of untested content, limited/missing instructions, empty rooms, broken text, or halting bugs.

Everything in the WIP builds will later be included in regular Private Build releases.
