Encounter the Wyvern Male, a monster who is eager to turn you into his breeding mate. He'll take good care of you, ensuring you're knocked up with eggs and milking your four large tits when they grow too heavy. The wyvern is quite a dominant partner, and will remind you of your place... and thanks to your new breeder instincts, you'll find yourself becoming quite submissive to him and his dual cocks. He has about 7k words of content (roughly the entire length of Chapter 2!) for a fun variety of scenes.

Modders also gain a range of new tools, including the ability to create LUA powered monsters and entity-to-entity communication.

Become a female breeding wyvern in the newly released r33 build. Fight against (or give into :3) your new mating instincts as you become a horny quadruped with a huge, egg-filled belly.

This artwork is by   ghostbun and is the first ever fan art for the game (so exciting)!

Ghostbun describes the premise for this piece as imagining what would happen in a ‘bad end’ where the player was too busy laying eggs to leave and had no choice but to submit to being Nixie’s lover forever.

You finally make contact with the shadowy Baosheng Group and discover Krista is becoming a cowgirl. Will you return her to human, send her to the farm, or keep her for yourself? These three different endings will greatly affect the future of VCiV.

Also includes proper tracking, display, and save/load for the Faction Point system.

* Shark TF - Become a powerful anthro shark!
* Tease system allows NPCs to tease you based on your new body.
* Octomaid, a half-octopus sea monster who knows just where to put those tentacles of hers...

Full blog post here, including some more details on the tease system. https://skycorp.global/2018/06/r31-.....-tease-system/

First, check out this cool new logo that Neb and I made:

https://skycorp.global/2018/06/new-.....shark-tf-soon/

Also, the next build is coming up soon and will include Anthro Shark TF and an accompanying Shark Tooth Necklace. It's the very first bit of content for what will eventually be Chapter 7, an aquatic-themed mission that takes place at the city aquarium. Based on previous chapters, you can probably make a good guess as to what happens when you visit the aquarium ;)

r30 is released, including new transformation features for modders. A Wolf TF sample mod is available to demo the new quadrupedal/paw support for modded transformations. Also, don't forget to check out the Dragon Queen enemy mods by Saint!

New build! r29 adds support for Permanent Tattoos that make you more obedient, lusty, or cause other effects.

http://skycorp.global/2018/04/r29-p.....anent-tattoos/

r28 is now released and features a piercings system for wearable piercings that cause various effects to your character.

Want to force yourself to always be lusty, or prevent your breasts from ever decreasing in size? Or wear one to get rid of those pesky attack options so you have to submit to your opponents...

http://skycorp.global/2018/04/r28-p.....s-and-aspects/

There are now three options during character creation to decide your initial acceptance rate. Each option has its own story to go with it, along with an explanation of the acceptance system. One of the options even lets you TF Becky some more ;)

Can you steal the treasure from the spider nest and escape? Or will the spiders get the best of you and transform you into their mate, forever filling you with brood after brood of spider eggs...

The new Spider Dungeon map demonstrates the new support for Map Mods, allowing you to create your own maps to explore in the game.

The Underworld r25.01 is now released - I accidentally broke the Dinoian chapter in the previous release, so if you had trouble with that, please grab the new build.

Also includes some other misc dinoian chapter text fixes & save fixes.

http://skycorp.global/2018/02/r25-0.....dinoian-fixes/

r25 is now released and adds a number of features requested by modders.

You can also check out our first user-created transformation (Pig TF by Luxious) if you like weight gain stuff, including both a Pig King enemy to fight and a cursed transformation pendant.

http://skycorp.global/2018/02/r25-r.....dder-requests/

You can now mod your own transformations into the game, including the first transformation mod: Anthro Giraffe TF. The r24 build also includes a new auto-login system which will be especially useful for Android players, along with an update to the game's business model.

Additional details on the blog: http://skycorp.global/2018/02/r24-t.....ormation-mods/

r23 is now released to all private backers and includes the ability to mod in your own items and clothes into the game! These can be simple text-only mods, or can be driven through LUA code. There’s a number of new sample mods available, including the cursed weight gain pendant which will cause you to gain weight continuously.

http://skycorp.global/2017/12/r23-m.....s-and-clothes/

This release for WIP backers contains the basics for the new LUA modding framework, which expands on the existing Monster Mods system to add a framework for players to script whole new objects with code-driven functionality.

Chapter six: "Dinoian Desert" is finally complete and ready to play! r21 is available for download for all full game / private build backers at the researcher intranet (@ skycorp.global) in both SWF and APK flavors.

This build includes the release of:

Dino Chapter

At the conclusion of chapter five, you incapacitated Thornton by transforming him into a catgirl, leaving him trapped to work in Mulberry's strip club while you steal his identity. You're now able to sneak into his convoy, which will allow you to cross the vast underground desert to scout out SkyCorp's research laboratories for the rival faction, VCiV.

What should have been an easy ride across the desert turns out to be much more than you bargained for. The convoy rides on specialized creatures that are genetically engineered to withstand the tough conditions of the desert. These dinoians could best be described as a distant anthropomorphic cousin of a velociraptor, or perhaps some sort of wingless riding dragon. One of them, Hanako, is planning her prison break, and you haplessly stumble into her plans.

Soon she's stealing your identity. She forces you to wear her old leather bindings, transforming you into a dinoian that looks just like she used to. She had unintentionally acquired the reputation of convoy slut, and now that you have her identity, she intends to make sure you live up to her old behaviors so as to not be suspicious. Every time you disobey her, she increases the size of your cleavage, making you hornier as you're forced to expose your nearly-naked body to the world as she rides you. To make matters worse, thanks to your monstrously large dinoian vagina, you won't derive any joy from copulating with humans -- so your body will work against you to force yourself to mate with your fellow beasts. But they're in a similar predicament, former humans trapped in lusty bodies that have no choice but to serve their riders and their base desires.

Try as you might, dinoians are forbidden from speaking thanks to their vocal cords which can only make animalistic noises. Though you desperately want to explain your situation, no one can understand you. Even removing the bindings themselves is impossible as they self-replicate to ensure you can never be freed. Stick around long enough, you'll start to enjoy serving your rider. You may even begin to enjoy being tied up with your wrists bound, further restricting your opportunities for escaping this life.

Will you succumb to your dinoian need to be filled up and lay clutch after clutch of eggs? Or will you find a way to escape your fate and complete the mission?

Backstory is revealed about the history of The Underworld, along with the factions that vie for power inside it. Three endings, one for each faction, are available -- each with their own puzzles to complete. Can you find all three?

Clocking in at a massive 30,000 words, this chapter is nearly three times as long any that has come before!

Frog TF

Now the frogs in the swamp chapter can now transform you into one, too.

Frogs and slugs will leave a trail of transformative slime behind them. As frogs naturally gain weight over time to get that nice frog belly, that can eventually cause their movement to be difficult. At larger belly (and optionally breast) sizes, it will drag on the ground beneath them and sometimes get stuck in the slime as they travel. If you go farther and intentionally max out belly/breast sizes… good luck moving at all.

UI Updates

The new layout is DPI-aware, and is much better for mobile devices and high-DPI PC screens. The extra width on the buttons is easier for fingers, and gives a bit more readable button text space on PC too. Also, when you start the game, the character stats are no longer shown until you’re in gameplay. The map and self description panels size themselves intelligently, and at low res, the self description panel becomes a separate button.

Waiting

A button now let's you wait for the next turn, instead of having to move back and forth repeatedly to pass the time.

---

Finally, I'd like to say thank you for everyone's kind words and encouragement during this massive chapter's development, whether that be in blog comments, discord, or wherever. I've never tried writing anything this huge before, and I couldn't have pulled it off without you cheering me on. So thank you, and I hope this chapter brings you much enjoyment.

r19 adds support for saving game progress. The Underworld uses cloud saves so you don’t have to worry about losing your savegame due to Flash cookies going missing. You can resume play between browser clears, incognito mode toggles and even across devices. For more details, please see the full blog post here.

Monster Mods (Private build feature) Researchers now have access to a new debug tool that allows them to create their own enemies. Use the Debug Monster Control Panel to input Monster Code. A new monster will then be created in the adjoining room. Monster Code can be generated without programming knowledge using the SCLab utility. Researchers are encouraged to post their monsters to the wiki.

New Enemy: Male Spider A new enemy has been discovered: the Male Spider. He traps unwary victims in his web and transforms them into female spiders.

The male spider is a tough opponent. A level 3 player with full health & empty lust can usually take him on, but any status effects (eggs, heat, etc) will tip the balance in his favor. It’s very difficult to get out of his web, so arrive fully prepared unless you want to become his mate!

He weighs in at approximately 1900 words and is implemented using the new Monster Mods system (copy his Monster Code from the wiki and paste it into the control panel’s input screen).

Custom Name Entry Research subjects can now enter their own names instead of using default assigned ones. Both masculine and feminine versions will be prompted for. If the subject’s sex changes, then they will start to refer to themselves using the alternate name upon reaching 100% acceptance.

Research staff can download r18 from the private employee intranet as either SWF (Flash) or APK (Android).

Attention researchers, a new species has been discovered!

A new cursed pendant in the debug room has the power to transform test subjects into anthro black widow spiders. After exposure, test subjects will no longer be able to stand upright, but will instead be forced to crawl on spider legs and will grow a huge, bulbous opisthosoma-butt.

Spiders are a strong species. Thanks to their razor sharp appendages, they are capable of performing combat strikes with 20% increased damage. This damage comes at a cost. Due to their short stature and octopedal motion, the female’s breasts will swing below them as they move. Large breasts will rub against the ground, driving arousal whenever they move. Extremely large breasts will occasionally prevent movement entirely.

Lust will have to be carefully managed, as the black widow’s opisthosoma-butt is so large that she will be unable to reach her own vagina to let off steam. Instead, the black widow will have to find a partner… but she must choose carefully.

When spiders engage in sex with a male partner, they stand a significant chance of becoming pregnant with a huge clutch of eggs. When pregnant, the spider’s belly will fill with eggs and become massive. The belly hangs under the spider, and at large sizes will impede the spider’s egress from predators and leave it vulnerable to attack. After a short incubation period, the female is forced to lay eggs. Regardless of her wishes, this cycle repeats several times until her supply of fertilized eggs is eventually exhausted. Finally her work is complete and she can return to normal proportions… at least until she is mated again.

Currently there are no males in the open world accessible dungeons, but researchers can use the debug hub to teleport to willing males in the dragon temple.

Research staff can download r17 from the private employee intranet as either SWF (Flash) or APK (Android).

R16 is now released. It adds mobile/touch functionality to make it easier to play the game on phones, tablets, and other touch-based devices. It also introduces APK builds for Android devices.

This is a private build, but these mobile features will be available to public build players in future.

See the blog post for full details: http://skycorp.global/2016/01/r16-mobile-mode-apk/ Enjoy!

R14 is released, including a community suggested TF. Please enjoy this release!

Horse TF
Use either the horsepills (hospital shop) or the cursed horseshoes (Jimmy’s shop at SkyCorp) to become more equine.

Male horses will grow a massive horse dick. As with all the more extreme TFs, you may find it more trouble than its worth. When sheathed, it’s sufficiently large enough that it will trigger automatic lust increase. And if you become highly lustful, it will extend out of its sheath to double its length and increase its girth. This size increase will destroy any pants you’re wearing, so hiding in urban areas will be tough.

When extended, your horse dick will be long enough to enjoy autofellatio during masturbation.

Warning: due to the extreme nature of this TF, you may find it difficult, perhaps impossible, to reach the Doc and become human again. Wearer beware.

Additional note: The horseshoe is the first non-neck TF item, which means it can be worn at the same time as other TF items. However, sometimes two cursed TF items ‘fight’ over specific areas of the body to claim, so you may want to stick with just one.

Tiger TF
Tiger TF is a more furry version of the Cat TF, but without the effects of going into heat. Tigers have three rows of nipples / breasts. Find tigernip in the grocery store and the tiger pendant in Jimmy’s shop in the SkyCorp office.

Turkey TF
New turkeys will find their arms transformed into wings and their belly gaining weight fast. Wear the Turkey pendant in Debug Curse Room 2 (south, then west). Happy Thanksgiving to players in the states!

Shopping List
Unlock all items in the shops instantly by using the shopping list in the debug room.

See the skycorp.global for a list of known bugs & more info: http://skycorp.global/2015/11/r14-r.....-tf-turkey-tf/

Chapter 5 (r13) is now released for backers. In this chapter, you're sent by VCiV to infiltrate a strip club. Unfortunately, the only way in is to become a stripper yourself, and you'll need to be a convincing one in order to find and neutralize your target. The problem? Most of the people who work here quickly end up becoming catgirls. Will you be able to finish your mission, or will you become a permanent employee at the club?

Along the way, you'll also learn a few new bits of one of your favorite character's back story and have your first glimpse of a whole new mysterious faction vying for power in The Underworld.

This chapter is the biggest one yet with over 12,000 words and 50 new rooms to explore. Read here for a story snippet: http://www.furaffinity.net/view/16845522/

A new release of The Underworld is out for backers! It adds:

Elephant TF - Transform into an elephant (will cause weight gain)
Cat TF - Transform into an anthro cat (will cause extra nipples/breasts)
Multibreast TF - Customize how many rows of breasts you have.

Five new TF items have been added in total. For more information you can see the release notes or check out the private builds information.
