r51 – Alpha Slugs & Become a Breeder

1080p:  Pg 1, Pg 2, Pg 3, Pg 4
Full HD:  Pg 1, Pg 2, Pg 3, Pg 4

r51 is now released and introduces a new enemy and a couple new features.

Alpha Slug Doms

The alphaslug is a much expanded shemale version of the original female titslug enemy.

Much like the female titslugs, if you lose to her, she will transform you into a titslug.  The alpha slug improves on this with an expanded transformation sequence for a more sexy and detailed slug transformation. She may also try to make you into a breeder slug (or breeder frog, if you show up as a frog).  Breeder slugs(/frogs) can actually get knocked up by her, and she’ll enjoy stuffing her large cock into your breeder slug pussy and filling you up. As slugs don’t have hands, it’s difficult for her to get herself off… fortunately breeders like you are available and so she won’t hesitate to make good use of you~

With your growing egg-filled belly getting in the way, you’ll find breeder slugs have a more difficult time getting around than even regular slugs. But since you’ll be stuck living in the swamp with your new alpha slug mistress, you won’t have to worry too much about mobility. 😉

She comes in two varieties: hard dom and soft dom.  Both function the same, but with slight text variation to reflect a more caring or more rough attitude.

She has several scenes: defeat, player’s slug transformation, oral victory, vaginal victory, turn the player into a breeder, ownership/marking and misc actions; totaling 8,500ish words (more than all of Chapter 2 had originally!).  Her scenes also support speech limiter alternates and low/medium/high acceptance variations.

The recommended way to meet her is to Chapter Skip to Ch 7, take the swamp quest from Malory including a level limit to be levelled appropriately for the chapter, then head to the sewers and fight your way into the extended dungeon.  Once you find an alphaslug in the procedural dungeon, you can lose to her to begin her custom transformation sequence scene.  However, you can also encounter her already being a slug or frog to keep those forms.

Get Owned

Want to commit to one alphaslug in particular? Your alphaslug would love that and will try to mark you as her own.  If you let her leave her cock scent on you, it’ll signal to any other potential alphaslugs that you’re already claimed by her.

Accepting an alphaslug as your owner is optional, however, it will open up some new behavior with that particular slug.  The game will refer to her as your Mistress and she will have her own individualized (procedurally selected) name.  Other alphaslugs will recognize her scent on you and be unable to claim ownership over you (though you can still interact with the other alpha slugs as regular enemy NPCs).

Your alphaslug will behave a bit differently than others: instead of attacking you on sight, your owner will give you a friendly greeting.  However, she’ll still make it clear she’s the Alpha, pouncing on you whenever she gets horny.  Since she gets horny from movement due to all those tits rubbing against the ground, as well as exposure to your breeder pussy scent, this will happen a fair bit.

Your owner will try to make sure you stay in either slug or frog form, as befitting your new status as one of the swamp denizens.  She’ll even follow you around to make sure you don’t leave the ‘safety’ of the swamp.  (She doesn’t protect you from the other horny denizens, rather considering you more a free public use slut she’s responsible for keeping around and has first dibs on.)

It’s fully safe to enter/leave the procedural part of the dungeon with her, as she will not be deleted out of the procedural area like regular entities are upon door closure.

Become a Breeder with Breeder Piercing / Breeder Tattoo

It’s now possible to become a breeder.

Becoming a breeder will:

  • Give you a vagina of at least average size, if you don’t already have one.
  • Increase your breasts to least D-cup size.
  • Remove your cock, unless you are wearing another item that would typically prevent that (horseshoe, cock ring)
  • Makes you extra fertile
    • Forms that normally can get knocked up (ex: whoredra, dino, etc) have an increased chance of being knocked up.
    • Forms that normally can’t get knocked up (ex: slug, frog, etc) can now be knocked up.
    • This may increase game difficulty or get you stuck in one of the chapters, etc.  The breeder system is intended as not-main-progression/DLC, and thus getting stuck as a knocked-up breeding catgirl stripper, etc is considered a feature, not a bug 😉
  • Causes your pussy to emit breeder pheromones.  This manifests as a small amount of lust damage in nearby enemies.  The effect is relatively slight, at a maximum of 15% lust damage per enemy — however, your alpha does enjoy that scent and might decide it’s breeding time~
  • Develop milky tits during pregnancy

Become a breeder by any of the following routes:

  • Get a breeder pussy piercing from the piercing shop in Haven (cursed, but removable)
  • Get a “BREEDER” womb stamp tattoo from the tattoo shop in Haven (permanent)
  • Get a breeder womb symbol from the tattoo shop in Haven (removable via TF)
  • Or, let an Alpha Slug have sex with you vaginally to gain the womb symbol (removable via TF)

The non-permanent breeder aspects can be removed if you transform to a form with no vagina.

Note – the breeder system is currently completely unrelated to the wyvern breeder TF.  In future, I might combine the two separate systems into one so the features of both can be used (ie: teases, slow pregnancy cycle, self lust penalty).

Other Changes

  • Egg laying as a slug now has custom flavor text to handle their unique body
  • Activities system allows enemies more flexibility in what actions they take, which the Alpha Slug has been designed to use.
    • (In future, more enemies should be able to use the same behaviors that Alpha Slug does (so could potentially see other doms that you can ask to be your Owner, etc))
  • Fix some Ch 6 bugs that didn’t prevent player leaving certain locations.  These were likely introduced by most recent update (but possibly never worked in the first place)
  • Fix bug where titslug masturbation would show unknown limbs when horny and needing to lay eggs
  • Slug TF takes one extra step longer
  • Fixed ancient Ch 2 typos
  • Begin tracking more NPC metadata like pronouns & hard/soft
  • Clean up teleport/scene logic between forced tf sequence scene / map scene
  • Hard dom / soft dom variation system for gametext / integration for alphaslug to support it
  • Entities can have different names between what’s shown in the entity list and what they refer to themselves as in dialogue

And relevant for modders:

  • Text parse tester now supports Hard Dom / Soft Dom / No Dom test setting
  • New text variables to handle NPCs, ownership status, breeder status, breast size, etc…
  • Remove formatting system to make it easier to do long strings of text IF’s
  • Various monster properties getters are now available outside the monster object

r50 – Farm Extended (VCiV Ending); Shemale Dom Alts

r50 is now playable for all active subscribers and introduces…

Extended Play for Farm’s VCiV Ending

In the previous update, I introduced some content to revisit the characters from The Farm and see what had happened to them after the SkyCorp ending.  Today’s update does likewise for The Farm’s VCiV ending route.  In 3,000 new words, see what happened to Micky, Emily, and Sasha.

Easiest way to access this content is via Chapter Skip, under the “Extended Farm (VCiV Ending)” option.

Note – Micky in this route will be found in the extended meadow (the procedural dungeon area).

Second note – Unlike the other ending route, there is currently no way to escape from this ending (unless you sneak in some items in advance).  Hope you like being a milky cow forever 😉

Shemale Dom(s) for Farm

In the VCiV post-ending content, a new minotaur has taken over The Farm.  Her name is Doris, and while she is mostly analogous to Micky, she does have two new exclusive scenes for her (one lore, one horny).  Her cum also has the special property of permanently increasing your milkiness.  If you get fucked by her too much, you won’t be able to take more than a few steps away from a milking machine~

In addition, you’ll also find Horse Women in the extended meadow area (basically shemale genderswap version of Horse Men).

Note – if loading an old save, may need to re-enter the farm to trigger Doris taking it over.

Bug Fixes

  • 129: Hard lock discovered in Return to The Farm content
  • 109: Multiple KritaCows

10 Years of The Underworld!

This weekend marks the ten year anniversary of when I started work on The Underworld!

The original r1, with no map system or UI scaling

When I released the initial version, I didn’t expect how much people would enjoy the game or that they’d want to play more.  I’ve been very encouraged by the positive comments and patronage over the years.

There’s been 83 releases total.  Here are some milestones:

  • Feb 9, 2014 – Started work on game (based on oldest surviving file)
  • Aug 13, 2014 – First initial announcement about the game
  • Aug 16, 2014 – First test build sent privately (15 downloads)
  • Oct 14, 2014 – First public build posted (11,322 downloads)
  • Nov 11, 2014 – First sale on BMT
  • Apr 10, 2017 – First Patreon backer
  • Apr 24, 2017 – Patreon launched
  • July 25, 2017 – Adobe announces end of Flash (oof)
  • July 31, 2017 – Discord created / first message (“Test”)
  • Feb 2, 2018 – Subscription
  • April 16, 2020 – Started work on new engine (which happens to be the 1000th code check-in)
  • May 16, 2020 – 1000 people in Discord
  • June 24, 2021 – First WIP release of new engine with chapter content playable again
  • August 5, 2023 – Port work for the new engine done as TF Mods added (the last of the remaining major features from the old engine)

After rewriting the entire game in a whole new programming language, the game is better than ever!  Today we’re up to 27k registered users and 1.3 million gameplay sessions.  Back when I first started this, I never thought it’d have the following it does today.

Thanks to everyone who has supported me on this fun and exciting journey 🙂

r49 – Return to The Farm (Procedural Extended Play)

In the latest build, you can now return to The Farm and explore a procedural farm-themed dungeon.  In addition, one of the endings for the farm chapter (the SkyCorp ending) has a couple new story scenes (~3,000 new words) so you can see what Sasha and Isabella have been up to in the intervening time.  (I have plans for a future update that will also cover the VCiV ending in a similar way).

After getting an ending for the Farm chapter, the Extended content opens up after beating the Strip Club chapter.  Quick start options for both endings have been added to the Chapter Select screen.  For the SkyCorp ending, if you’re re-caught in the farm, you will be forceably transformed into a cowgirl once again.  Micky has a new intro if he re-catches you directly.

Security has been stepped up, so escaping your milky fate will be notably more challenging.  Beware — if you indulge in the bovine growth hormones to up your milk production, it’ll become impossible to move far away from the milking machine at all!  It is definitely possible to get yourself trapped on the farm while in Extended mode.

Similar to past procedural dungeons, you can change the generation parameters to make larger or smaller dungeons by visiting Malory in VCiV HQ before entering the farm.  By doing this, you’ll also have a specific intel objective item to seek out in the procedural dungeon and return to her (assuming you don’t just give in to your new life~)

Hybrid Cows

In addition to becoming a cowgirl again, you now have the option to become a hybrid cow.  If you return to the farm as another species, for instance a fox, you will be able to ask Micky to change you into a foxcow.  Showing up as a Dragon Queen will result in you becoming a Dracow Queen, and you’ll indeed both make milk and lay eggs~

Typically, hybrid cows will end up with milky F-cup breasts, including an extra row of breasts, an udder, some kind of tail, cow ears and non-dexterous hooves.  The species name you’re referred to as will also be updated to include ‘cow.’

(This should work for most of the species in the game, but certain edge cases like supporting non-verbal speech hasn’t been done yet for the farm enemies)

Misc

  • Added back button to Chapter Skip screen (finally after 9.9 years 😅)
  • Modding:  Fixed a bug where Player.incOverweight function was not passing the optional hyper parameter

r48 – Gym Rat (Weight Gain Dom)

r48 is now released to all backers and includes a new mob, a way to re-encounter Valeska, and assorted fixes.

Gym Rat

A new fightable enemy has appeared in Haven:  the Gym Rat.  This athletic female wields a double-ended dildo with weight transfer powers.

If you lose combat against her, she’ll fuck the pounds into you via the double-ended dildo, leaving you chonkier every time you meet her.  She soon realizes she can eat as much food as she likes and just stuff the fat into you, instead.  Your progressively growing weight becomes a sign of her dominance over you as you struggle to beat this powerful enemy.  This rodent loves playing with your new chub and teasing you about how heavy you’re getting.

Not content with only fattening you up during encounters, she’ll also try to convince you to wear one of the cursed collars that will transform you into one of the thicker species (Panda, Elephant, or Turkey) — forms that keep piling those pounds on regardless of your efforts.

The weight transfer dildo can fatten you up to the point where walking around becomes difficult, and eventually impossible entirely.  (Note: currently immobilization just drops you off at the gym so you can (slowly) work off the pounds, though I’d like to add some more immobilization activities/options in future.)

If you defeat her in combat (no easy task given her high level), you can turn the tables!  Flip the dildo the other way around, and now you’re adding pounds to her.  If you get her fat enough, she’ll start to lose combat effectiveness, and eventually immobilize… making her stuck like that forever.

There’s around 3,600 new words for Gym Rat content, including variations to properly recognize different acceptance levels and be compatible with vocal limitations.

Re-encounter Valeska in the Dragon Temple

If you are a collared Dragon Queen, you can now get knocked up by Valeska (from the previous update’s Procedural Dragon Temple) as many times as you like!

After you have become a full Dragon Queen and collared by Valeska, you can use the altar in the Hatchery to re-trigger her breeding sequence.  The alternate intro to it is around 1,200 new words long and teases the player a bit about how the whole temple knows you are a horny, egg-filled Dragon Queen now~

Misc Improvements / Fixes

  • Fix bug where Valeska fails to put the level limit piercing on you.
  • Butt size adjectives now consider overweight amount (in addition to also considering breast size as before.)
  • Text spacing fix for when increasing or decreasing weight for belly shirt lift-up stage.
  • Added new text variables for checking player weight.
  • #121 – Fix bug where dragon servant would cause instant full term pregnancy if player had a type of pregnancy other than Dragon Queen.
  • Fix issue where going in and out of chapter select options was causing player to be overleveled / too far along in progression.
  • Fonts on the blog / intranet portal are a bit larger to more closely match in-game font size and generally be more readable.
  • #113: Fix for self examine textbox not resizing on window maximise (fixed in demo, also).

r47 – Procedural Dragon Temple

Return to the Dragon Temple and become an egg-laying Dragon Queen once again!

The temple has opened for new recruits, and they’ll take any human who wanders in.  Their transformation ritual/orgy will have you transforming back into an anthro Dragon Queen.  You’ll be dumped in the middle of a procedural, randomly generated dungeon. And if you don’t escape before laying eggs and being collared, you’ll be stuck as the new Dragon Queen permanently.

New Dom:  Valeska

In this update, you’ll meet a new character, Valeska.  This shemale anthro dragoness has been ordained as the temple’s high priestess by virtue of being the temple’s most virile biped.  This comes from the fact she’s a broodstud hybrid and has the equipment to match.  That semi-feral 18″ dragon cock and powerful haunches can keep filling a Dragon Queen for hours, yielding so many eggs you won’t even be able to walk for some time afterwards.  Not all the temple denizens are thrilled with a near-broodstud in such a revered position (there still being a lot of biped/quadruped social class dynamics, even amongst the changed population), but Valeska is just within the requirements to pass as a biped.  In any case, it’s difficult to argue with the results after seeing the size of your egg-filled belly and watching the egg laying counter in the breeding chamber increase with your every clutch.

Dragon Queen Pregnancy – Extra Large Belly Sizes Unlocked

Both Dragon Servant and High Priestess Valeska can now knock the Dragon Queen pregnancy up to higher levels (beyond 100lb belly).

Doing so will reduce player mobility and debuff attacks, and eventually reach a point where the player will be immobilized entirely. This also means Dragon Queen pregnancy is no longer rigidly tied to laying eggs at exactly 100lbs, though this is only really noticeable for your first clutch or you’re carrying more than 100lbs of eggs.

So as to avoid overwhelming new players, extra large bellies only get triggered in the extended play content (not during Chapter 3).  Also, this feature is only implemented for Dragon Queen pregnancy.  The other pregnancy types are still tied to 100lbs — though this might be added in future.

New & Updated Scenes

This update brings around 6k completely new words, mostly focused in Valeska’s two long scenes.  The transformation ritual/orgy scene includes some small randomized variation — keep an eye out for what the other recruit changes to, as the initiate to your left has three different outcomes described.

In addition, the old scenes with the Dragon Disciple and Dragon Servant have been improved to support the player in varying states, such as different levels of acceptance and different species.  Temple denizens will try to capture humans, regular anthro dragons they tolerate unless attacked, and Queens they try to breed.

Also, there’s a Drakeling scene outside the temple to hint at the content inside.

How to Play

To initiate it:  Just revisit the Dragon Temple after finishing Chapter 4.  One way to do that is to chapter skip to Chapter 6, then walk over to the Dragon Temple, and lose a fight there.

Alternatively, and perhaps more fun from a gameplay perspective, you can initiate the new content through the procedural missions system.  Chapter skip to Chapter 6, go one room north to speak with Malory and initiate a side mission.  Here you can customize the dungeon and make it larger/smaller, etc (make sure you choose ‘Temple’ as the location).  This can also put a level limit piercing on you to make the challenge a bit more balanced so you don’t have to intentionally lose a fight.  Then walk over to the dragon temple and it’ll use the settings you configured.  See at what dungeon size/settings you can manage to get in and out with the intel, and at which dungeon size/settings you get stuck as a Dragon Queen forever~

Temple Tips & Notes

  • If you’re captured as a human, the result of the transformation ritual is slightly randomized.  There’s currently a 90% chance of ending up as a Dragon Queen and a 10% chance of ending up as a regular dragon.  If you already have transformed a bit, then it’ll use that — so you could take one step of regular dragon transformation via the debug rooms, get captured, and then that’d force a regular dragon TF during the transformation scene.  (Though not written yet, I left it open so that potentially in a future update, you could end up as a drakeling or busty quadrupedal broodwhore.)
  • You can wander into the reopened dungeon as any species — for instance, as a fox.  They won’t be able to transform you and do Dragon Queen things to you, but you can still fight through the dungeon if you like.
  • If you want to really lose, you can level limit yourself to level 1 instead of level 2 via a tattoo.  The side mission system has been improved to recognize tattoos of harder difficulty.
  • Note – Revisiting Nixie isn’t possible due to Reasons, though she is referenced in the new content.  Mostly you should expect to be interacting with the guards, servants, and Valeska in this update — they will be happy to keep you company 😉

Level Limit Tattoos

The tattoo parlor now lets you choose ‘Easy’ tattoos of varying rank — so if you want to cap your level at a specific threshold, that is now possible.

Modders:  Random Text Variable

Text Variables now supports a RANDOM variable, which allows you to select a block of text randomly.

Misc & Bug fixes

  • Dragon Servant now has 9hp instead of 3hp, making it so they don’t instant-lose when fighting you pre-TF.
  • There’s a new ‘beacon’ system that makes it easier for code to find particular rooms dynamically.  It’s not yet exposed to the modding system, though.
  • Fixed:  Chapter Select – Ch 5 doesn’t complete Ch 4 content (#114)
  • Fixed:  Monster Machine crash (#118)
