The Underworld
by SkyCorp

The Underworld is a text based forced transformation game for mature audiences including erotic content such as: furry, monstergirl, male to female (MtF) transformation, oviposition, lactation, and more. Along the way, you’ll meet a wide cast of characters across the three factions that each have their own ideology about how to deal with people different from themselves. Your actions will determine which faction achieves victory, and by extension, the fate of humans and hybrids alike.

r36 - Mermaid TF & Water (Private Build)

Become a lusty, buxom mermaid in r36!  That heavy mermaid tail will keep you stuck in the water, and being a horny merslut, lust attacks will hit you for double damage.  But unlike humans, you can breathe underwater.  Currently, you'll be stuck in a test pool with the octomaid, but she knows just how to keep you company with those tentacles ;)

Full post here.

r35 - Wyvern Male & LUA Powered Monsters (Private Build)

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.

 r32 - Chapter 7 Intro (Private Build)

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.

Full release announcement here.

r30.03 - New public demo build

A new public demo build is now available!  Since the last demo build, this includes:

  • Tattoos & Piercings system - Get one to force yourself to always be lusty, or prevent your breasts from ever decreasing in size.  You could even get one to get rid of those pesky attack options so you have to always submit to your opponents...
  • Choose initial acceptance level - There are now three options during character creation to decide your initial acceptance rate and how you treat others. Each option has its own little intro story to go with it, along with an explanation of the acceptance system.
  • Better organization of inventory UI.
  • More reliable keyboard shortcuts.
  • Numerous other small improvements and fixes.

r30.01 - More Modding Support / Wolf TF (Private Build)

r29 - Permanent Tattoos (Private Build)

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

r28 - Piercings (Private Build)

This update 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...

r27 - Choose Initial Reaction (Private Build)

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 ;)

r26 - Map Mods / Spider Dungeon (Private Build)

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.

r25.01 Dinoian Fixes (Private Build)

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

r25 Modding Requests (Private Build)

r25 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.

r24 Transformation Mods (Private Build)

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.

r23 Mod Support for Items + Clothes (Private Build)

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.

r22 (Public + Private Builds)

The main new content for public build players in r22 is Frog TF:

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

4000+ words of chapter 2 content including different scenes when the Naga Queen defeats you based on what form you’re in. The minions are a bit smarter too, and won’t try to transform you if you’re already a frog or slug (unless you’re not 100% in that form, in which case they’ll try to re-transform you if you’re of the matching species). Frogs and slugs also now leave a slime trail wherever they go, which can re-transform you if you use it (it’ll eventually evaporate). If you track slime into Nixie’s shack during the swamp quest, she’ll comment on you making a mess of her place.

Frog form is another in the all-fours category, since frogs can’t stand upright. 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.

Additional New/Updated Functionality:

  • UI Updates / DPI-aware layout
  • Wait Button
  • Entity Selector
  • Retuned Dragon Queen oviposition rules
  • Added reduce cream to hospital shop, and as an item occasionally dropped by foxgirls.
  • Misc text fixes

r21 (Private Build)

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 in both SWF (PC) and APK (Android) flavors.

This build includes the release of the 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!

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.

Attention! All SkyCorp employees are to be alerted of outbreak of VIR-819 in Mulberry and surrounding areas. Original infection of virus into human populace traced to -REDACTED-.

Progressive exposure of the virus causes mutagenic effects in human subjects. Infected are highly contagious, causing additional mutagentic effects on humans they contact. So far, documented mutagenic effects have included: hybrid fox transformation, hybrid dragon transformation, increased libido, gender changes, and oviposition. Due to the chaotic nature of VIR-819 and the denizens of the Underworld, the infected are likely to encounter all prior mutagenic effects listed. Additional mutagenic effects are expected as the virus evolves.

SkyCorp has lobbied and received regional government funding to build the Underworld, an underground complex where infected creatures are mandatorily required to relocate to upon discovery. Investigative journalists have indicated this network contains at least one shantytown, a sewer dungeon, some sort of mysterious temple, and various connecting passageways. However, SkyCorp personnel must strictly occupy only the town of Mulberry and other overworld areas for their own safety, unless they have received designated security training. Additional areas are expected to be found as exploration of the network continues in future.

Employees should encourage Mulberry citizens to be ever vigilant of signs of infection. Infected creatures have been known to mask their mutations with clothing and feign humanity -- but these creatures are dangerous and must not be allowed to run free due to their changed nature. SkyCorp has identified at least one suspected sympathizer in town who has been providing aid.

Employees interested in researching The Underworld/VIR-819 are requested to download the training materials.

A recent copy of Adobe Flash will be required (Flash 11+), and employees are requested to file a summary report on their experience in Mulberry and surrounding areas. Prospective trainees are advised as to the early and experimental nature of this program.

not recommended till it drops the price. i probably wouldn't shell out that much for this unless it was highly praised, let alone having to pay that much per month. public/free version has far less content than the private branch and hasn't been updated recently.

Please don't play this game, don't support this developer, and don't encourage this kind of abusive behavior towards our community.

 

I had paid for this game years ago when it was still relatively new giving the author the benefit of the doubt.  It was expensive based on the state but also had some hard to find content that I really enjoy (forced non-human TF).

The agreement with that purchase was that I would recieve future content for free as I supported the game.  Patreon came out about a year later and things started to change.  The first change was to create what is effectively DLC, so that the developer could start charging for content other people created.  As if this wasn't irritating enough, most of the content was advertised on TFGS as new content, and not as DLC that required a subscription to get.

So I eventually caved, picked up a subscription as one piece of content was really appealing only to learn the dev has multiple levels of BS.  Instead of just having Patreon charge me up front and adding me automatically, a script has to run, and will only run near the begining of the month after I pay.  So even if you want to play the DLC content, you have to wait until the dev gets around to letting you...  So, after realizing I would have to wait a month (as this dev consistently puts out updates shortly after the month starts) I backed out of the pledge as I already didn't like that I was paying a second time for something that felt should be provided with the core game (if the dev wrote it) or for free.  This is literally the same way the players feel when day 0 DLC hits or when devs start charging for for player created mods, except, the game isn't out yet and yet it already has DLC...

As if this wasn't enough abuse to people that have already shown their support, I'm now locked behind a time gate for new content as I'm a legacy user...  Instead of showing respect for the people that were willing to overlook the obvious flaws, I feel like I'm getting spit on instead. 

 

This dev is a real piece of work.  Please do not support them.

A solid game completely ruined by a relentlessly greedy developer. Writing those words I feel like I'm talking about one of the big gaming controversies that happened this year, but instead I'm writing it about a fetish game. 

For some background, back when this game was first released it showed a lot of promise and I could see the potential for it to grow into something that could rival other games of this type, notably Corruption of Champions and Flexible Survival. You can even see my original post on this game on the second page of the discussion forum. Incidentally, most of the issues I raised there still exist, 4 1/2 years later. 

Anyways, I was caught up in the excitement enough to (somewhat foolishly) buy access to the premium version at the time, which involved a single (quite steep) payment. However, I was satisfied with the content I recieved and was thought of it more as an investment into the continued development of the game. 

Flash forward, and the developer has now switched to a paid subscription model more akin to a MMORPG than a singleplayer RPG-esque game with a moderate amount of content. Effectively, for $10 a month you gain access to the newest private version of the game. However, once that subscription lapses you not only lose out on new content added, but you also cannot play the singleplayer game you downloaded anymore. Private builds connect to a server to check your login credentials before alowing you to play. A side effect of this is that you cannot play if you are offline, even if you are a currently subscribed backer. So we can add always online singleplayer games to the list of gaming contreversies this has unwittingly ripped off. 

However, as an original backer, I got access to all these new private builds without needing a subscription. So while I very much disproved of both the model and pricepoint, it didn't personally affect me, and the content, while being slow to release, was still pretty good. But then he released modding. Initially, I was all for it. Crowdsourcing content can be a very helpful boon to games like this that have a solid foundation but lack content. But the trick is, in order to access the mods, you need to be currently subscribed to the game. That's right, we can now add paid mods to the list of greedy moves. That being said, this is actually worse than Bethesda though, because as far as I can tell, there is no compensation being shared with the mod makers. I would be paying Skycorp money to access someone else's content. 

And I would have to pay money. Because even though I was once of the first backers to the game, I do not have access to the mod menu. I would have to go and pay $10 a month JUST to access this new content. The final kick in the balls is how the developer now seems to be putting in new update sized content that he developed behind this new paywall he's erected.

Let's take a second and discuss what the game actually is in more detail. It's an open world RPG-esque game similar in scope to game like CoC and FS. The setting is pretty generic, basically what would happen if Umbrella was run by extreme furries. It's got a limb focused TF system like FS, and suffers similar issues with lack of detail or noticable player reactions in the majority of them. The story itself is probably the strongest point of this game, as each chapter focuses on one TF in much more detail. Overall, these sequences are well written and designed, and really where this game starts to come into it's own.

However, this is where the distinction in builds really gets felt. The public build is woefully out of date in comparison to the private build. Most noticably, it contains only one proper story section, while the private build is up to chapter 7 by now. As a result, the public build is incredibly low in content by comparison, and once you've completed that first story section (Maybe 10-15 minutes) you've basically seen all it has to offer in terms of good content. The rest is just padding and a feel undetailed TFs thrown in haphazardly. 

Strip out all the greed from this game and you have a very solid competitor to some of the largest games on this site. But all the greed that's being shoved down our throats takes that foundation and completely undermines it. There is no reason that the developers should not be able to profit from this game. Many on here rely on Patreon or similar to support them. But the key difference is that they don't undermine the quality of their own game to do it, and they price their games accordingly. This game, and the release schedule behind it, is in no way worth $10, let alone a continual $10 a month just to keep accessing it once you've started. 

Stay away from this game until the developer stops trying to squeeze every last penny out of players.
