Its storyline is based in a not-too-distant past of 2008, containing science fiction elements about a nanite-based virus outbreak and its mutation-inducing consequences. The game is based on roleplay and classic hack’n’slash combat, supporting both a web interface as well as a standard MU* telnet client.
- Fixed a park event soft lock that could leave the player stranded at the public hitching-post stocks without movement or fast-travel options. (David Silver)
- Added Inform’s ‘play on’ command as a one-way extended-play cheat in Trixie’s Cheats menu. (David Silver)
- Integrated Flexible Survival PR #2818, adding the source-backed Snuggle Fox enemy and infection behavior, Mistress Snuggle dialogue and progression, the Snuggle’s Loft location chain, and its navigation unlock. (David Silver)
- Fixed the external image-folder picker so Windows users can browse mounted drives such as D: instead of being confined to the AppData drive. (David Silver)

- Fixed the Lil Better cheat so it is a one-time permanent stat increase instead of a repeatable toggle. (David Silver)
- Fixed dialogue and persistent text panels so their wrapping width and text origin are enforced within the HUD column, reserving the right-side Quick Menu and scrollbar space even when inherited character styles are active. (David Silver)
- Reworked the responsive HUD around shared sidebar and bottom-tray boundaries so text wraps before the Quick Menu instead of being clipped beneath it, while all lower interface panels remain consistently anchored. (David Silver)
- Improved Android external image loading with API-appropriate storage permissions, automatic retries after permission changes, and an in-game folder/access diagnostic. (David Silver)
- Fixed enemies attacking multiple times during a combat round, and began correcting combat flow with related fixes and cleanup. (devSin)
- Fixed combat-victory narration on mobile by preserving the HUD-bounded text layout across nested Ren’Py contexts, preventing the text from running beneath the Quick Menu. (David Silver)
- Fixed responsive HUD text wrapping and added reliable Quick Menu scrolling so long text stays clear of the menu and the Infection section remains accessible on smaller screens. (David Silver)

- Refactored the dialogue, persistent-message, choice-tray, and compatibility screen plumbing to remove duplicated layouts and state-handling seams while preserving the existing desktop and mobile behavior. (David Silver)
- Fixed a crash when displaying a blocking persistent message by keeping viewport adjustments separate from scrollbar values, and removed duplicate legacy menu-screen definitions. (David Silver)
- Fixed the Give In to Infection action being blocked at full humanity even when the player had at least 50% infection coverage. (David Silver)
- Fixed the Latex Vixen Herm registration so its enemy and infection data agree with the authored form, including the 18-inch cock and apple-sized balls. (David Silver)
- Fixed transformations leaving newly created or legacy zero-measurement anatomy incomplete, and made full transformations transfer registered cock length, cunt depth, and cunt tightness values. (David Silver)
- Fixed body status displays so anatomy with a zero measurement is treated as absent instead of being reported with nonsensical 0-inch dimensions. (David Silver)
- Verified Grey Abbey Library’s fresh-game NPC roster against Inform and fixed Serenity, Icarus, Bernard, Bianca, and Sturm from appearing there before their source-authored recruitment or progression states. (David Silver)
- Removed Serenity and Icarus from the startup always-present library list and cleared all five NPCs’ default locations, preserving their later Inform-driven movement and recruitment routes. (David Silver)
- Fixed the specific-mutation cheat callback and combat callback handling so those targeted actions resolve through the correct live functions. (David Silver)
- Fixed gameplay text wrapping so the text column stays clear of the quick-menu overlay at the right edge. (David Silver)
- Renamed the quick-menu Quest Log button to match the quest interface. (David Silver)
- Audited dialogue and event chains for quest consistency, wiring Scopaesthesia, the wasp hive rescue, Segis upgrades, the Zephyr detector survey, the Sundered Dragon lab route, and the Station 69 discovery into quest tracking with consistent IDs, stages, prerequisites, and completion states.

- Added spoiler-stage coverage for the newly tracked quest content and fixed event-triggered quests so they start automatically when their event begins, without changing the existing player-facing dialogue text. (David Silver)
- Improved old-save loading by normalizing missing or malformed body-part infection data and keeping text input screens above the HUD as modal prompts. (David Silver)
- Added an inline quest spoiler browser covering active, available, locked, future, and completed quests, with separate Spoiler and Where? buttons that expand beneath each quest without leaving the list. (David Silver)
- Added player-facing quest-stage guidance across all registered quest stages, including encounter clues and visible choices, while showing only the stage currently relevant to the player. (David Silver)
- Added location spoilers that reveal recorded areas, rooms, movement triggers, random-event behavior, and matching rooms in the relevant area; follow-up and terminal quest-line status is also shown. (David Silver)
- Fixed the inline spoiler panel crash caused by Ren’Py interpreting stage labels such as [FUTURE] as variable substitutions. (David Silver)
- Added the ability to rename the player from the character stats screen and restored equipment-driven every-turn effects with save-compatible defaults. (devSin)
- Added the equipment screen to the quick menu, with separate backpack and equipment access, in-game equip and unequip controls, and event-driven item equip callbacks. (devSin)
- Improved the bunker storage locker with safer item matching, weight handling, sorted contents, and a dedicated modal storage interface. (devSin)
- Expanded companion support with traits, combat experience, assault prose, fight tracking, party-size enforcement, and summon or dismiss hooks. (David Silver)
- Added a compact local navigation map to the action tray, automatic registry-backed character and location art wiring, and fallback location-art resolution. (David Silver)
- Added German shepherd bitch heat-cycle support and corrected a rhino-cum crafting recipe to use the live item id. (David Silver)
- Fixed a compilation issue by restoring the Gus source content and removing the obsolete Feral Fox source file that was still included in the build. (devSin)
- Restored Angie content that was accidentally removed during the previous source update. (devSin)
- Fixed unimplemented NPC interactions crashing or leaving the location map stuck on screen by safely handling missing scene hooks and consistently restoring the location artwork. (David Silver)
- Fixed heat-cycle transitions interrupting fast travel and other turn-driven actions, removed the visible default heat placeholder text, and preserved infection-specific heat effects with existing-save compatibility. (David Silver)
- Fixed Angie’s catnip interaction crashing on the obsolete item-check helper, and corrected Feral Sea Dragoness and Smooth Collie heat-cycle code to use the registered infection-data interface. (David Silver)
- Fixed successful standard enemy retaliation crashing on shared monster HP state, and repaired Lyall’s three-Ogre combat sequence so its win, loss, and flee results return to the encounter correctly. (David Silver)
- Restored the Inform-defined Dry Plains enemy roster, including repair of empty encounter pools in existing saves and canonical Dry Plains registration for the conditional Horsemazon encounter. (David Silver)
[Backers] Arlene: The player’s one time fling turned Priestess of Kai Monah, Arlene handles the majority of the day-to-day affairs of your Dragon Cult. Featuring four sex scenes that change based on your gender, tail configuration, pregnancy status, ball size, as well as hir own gravidity Arlene is ready to service both herms and females alike. However, one of her scenes is female exclusive at the moment. Over time as your cult evolves Arlene will change with new scenes opening and some being removed as grows into hir role as caretaker of your Breeder Cult. Note: until the cult’s next update, this feature will not be implemented. In the meantime, breeding hir and your cultist will make it easier to expand your temple when the feature is added. [Sundered-Dragon]
[Backers]: Robin: A new event in the park, the “Easter Bunny Park Trail” allows you to find some chocolate eggs and even meet the bunny himself (Robin), for a little pile of eggs and a potential gay sex scene. He has a little bit of a tie-in wich Michaela the bunny from the forest, where he mentions her as well. [Wahn]
[Backer]: Ava: At long last Ava’s preg quest has reached its conclusion with several new walk-in events for both good and naughty kittens, as well as a special trip to the beach involving Kathy, Ava, and a few preg enthusiasts interested in your infection. Additionally, good kittens that have befriended human Drake will be regularly gifted with several food and drink items made by their cubs which benefit from the Junk Food Junkie feat at the end of their event chain. [Sundered-Dragon]
[Backer]: Minor fixes have been made to the Tainted Blade’s description.
[Backers]: Amy: You can now take Amy to the pet store and get her a nice decorative collar to wear (check her talk menu after she has grown up). [Wahn]
[Public]: Fixed main storyline bug that stalled progress around the new amount of nav points required.
[Backers]: Bald Eagle: The Bald Eagle enemy has been expanded upon, offering you a menu of options now after you defeat it. (Jerking On it, Fucking, Riding [anal/vaginal], Milking, or just driving it off. [Wahn]
[Backers]: Mul: Mul’s scene in which he visits the library has been updated the modern code, so it is less likely to bump more important scenes when arriving in the library.
[Backers] Cot: The player’s cot now has a MUCH lower weight. Considering the importance of sleep to players playing with survival mechanics on, it made no sense to punish the player for something they were required to have! [Voidsnaps]
[Public] Zea Bat: The chip damage in the Zea Bat fight has been slightly reduced. [Sundered-Dragon]
Break Water Heist: Join Galaxite and the Naxozaazthur as they raid a stricken supply ship floundering off the coast. Much like the ruined trawler event, you can expect to find a tough fight waiting for you, along with another chance to impress the dragon brothers. In addition, some special content has been added for those of you with pure blooded Margay Taur or Knight infections. [Sundered-Dragon]
Cyn (Fever Dream/Hallucination/Limbo Fox): A new creature will reveal itself in a walk-in event to those above level 20, who are touched by madness in a new, abandoned area at the Fair called the Ghost Fair. This includes a slight body horror, eldritch themes, Player X female and future player X Herm content. For those that manage to befriend this elusive creature, they offer a number of services, like the ability to recycle some items into XP or a unique currency which can be traded for useful equipment. [JP]
Hazel: You can now introduce Hazel to the wonders of sex if you talk to her after her trip to the Museum. [Prometheus]
Point Nemo: In possibly one of, if not the largest event ever added to Flexible survival, you can now take another step on your path to ascension, meet your patron, and get a brief glimpse of other upcoming content. This event features six orgy scenes for herms and females centered around a bawdy crew of Pirate Sharks with some extra content based on whether or not your character is pregnant. Four potential four TF scenes, three of which are player exclusive and will change based on where or not you have both the Vore Predator and UB pred feats. As well as an NPC based M to F/H TF and sex scene. Several new characters have also been added, some of which are recruitable as priestesses and servants for your personal dragon cult. [Sundered-Dragon]
Signpost: An in game wiki of sorts outlining all of Voidsnaps’ has been added to the swamps. It’s a good place to browse if you’re looking for a specific character or fetish! Only includes Voidsnaps content. Sorted by area! [Voidsnaps]
Bugfixes & Balance Patches
Zea Bat: The chip damage in the Zea Bat fight has been slightly reduced. [Sundered-Dragon]
Alistair (Noble Knight): You can now offer yourself to your knight. He’ll take on the challenge of “training” you with gusto and show you some kinky exercises to make you a better knight (and lover). [Voidsnaps]
Alistair: second introduction event that moves him to the Mystical Falls now has a 100% proc rate. Sorry about that folks! [Voidsnaps]
Dragon Harem: A questline to tame feral dragons. Help Soot capture them before they wreak havoc on your world! With sexy results (The dragons are male. 2 out of 4 curently available.) [Voidsnaps]
Argos’s Antiques: Another fix so that it’s navigable again. [Voidsnaps]
Beach Reunion: The follow up event to Holy Moly, this event can be found at the beach where you’ll learn Galaxite’s plans to plunder the city with the help of their many draconic children. Or take on the mantle of the Dragon Breeder, build your own flight, create kobolds to serve you, and potentially pull off the biggest steal of the apocalypse. [Sundered-Dragon]
Bug Fix: Thanks to some help from emerald, it should no longer be possible to accidentally wander into the Last Chance.
Ava and Alp 69: Belated seasons greeting eager breeders, despite some setbacks, Ava’s pregnancy quest is now more or less complete though a few changes had to be made to get the content to play nice with Inform. For starters, the event Breeding Materials has undergone a slight rework. By request, you will no longer be required to have the Vore Pred feat to view some of the special scenes with Dr. Medea. Unfortunately, the parasite turn in event chain has been cut due to issues with inform, in addition the item requirements have been removed. This has also necessitated a reset in the Alp 69 event to ensure the following content works as intended. If you have already done so in the last update, you’ll need to do so again to view the rest of the quest chain. [Sundered-Dragon]
Bug Fix: Thanks to some help from emerald, it should no longer be possible to accidentally wander into the Last Chance.
These are projects and commissions that our writers are committed to, something for you to look forward for the future.
Blanche/Sturm: Continuation of the multiple ways in which they can spend time together. [Prometheus]
Blanche: You can now encounter the initial event for Blanche and Sturm, with limited variations depending on personal taste (and with more to come). Given the currently limited options, the event will reset when you import your save. [Prometheus]
Carl: Various variable checks in other npcs that were interacting with Carl have been updated to be compatible with the rework. That should hopefully eliminate error messages on that front.

Writer for Hire / Commissions
Ava: The adorable kitty’s storyline is about to reach its penultimate phase. To start it, you need to finish her pregnancy play event chain. As a reminder, this walk-in has a small chance to play every time you enter her room while you’re a gravid female Margay taur, and requires you to have spoken to Kathy at least once. [Sundered Dragon]
Breasts: The game should now properly display both the start and end breast size.
These are projects and commissions that our writers are committed to, something for you to look forward for the future.
Ava: The voracious conclusion to Ava’s pregnancy quest is hopefully coming in time for Mayternity. Carl: Further updates of Carl’s content in the aftermath of the gritty soldier squad reboot are underway. [Wahn]

This includes a walk-in event in the Mysterious Store in which some Bastet-worshipers appear, followed by you then talking to Bastet to take her to visit their shrine. [Wahn]

Urik:
Some new scenes for the big orc daddy are coming soon, putting him in a dominant position with the player character (after you’ve befriended him, so not in an “I’m taking over” way).

Augustus
: A stern, somewhat cynical survivor with a soft spot for cats found at the Last Chance Motel. Drake can be transformed against his will with the help of his lover. Just don’t expect him to be happy about it. Current pairing: when transformed F/M with an extra scene for taurs. Baseline Drake has no scenes, yet. [Sundered_Dragon]Combat Seduction:
Enemies that end up at exactly 100 Libido should now also show the proper loss scenes.These are projects and commissions that our writers are committed to, something for you to look forward for the future.
Urik:
Some new scenes for the big orc daddy are coming soon, putting him in a dominant position with the player character (after you’ve befriended him, so not in an “I’m taking over” way). [Wahn]Carl: Continuing with the gritty reboot of the soldier squad, Carl’s intro into the library has been reworked, with more content between him and yourself instead of just dropping off the npc straight away. If you already have Carl in your import, you can talk to him to replay the arrival in the library and the choice to be made there. [Wahn]
Daphne: Light Typo Fix

Candy: He will now only mention Carl in an event if Carl actually has been recruited.
These are projects and commissions that our writers are committed to, something for you to look forward for the future.
Altus
: Penetrative sex scenes and interaction with other library NPCs. [Prometheus]Blanche and Woofs:
You should no longer be able to summon them as companions while out in the city. (Their hearing isn’t that good. Except perhaps Lumi’s, but she has things to do.) Requires being in the same room.Bugfixes & Balance Patches
Fang:
Alpha Fang should no longer have the option to involve Sandra in his sex scenes if you haven’t rescued the needy bunny girl.These are projects and commissions that our writers are committed to, something for you to look forward for the future.
Altus:
Despite Altus’s prideful ways, if left alone for too long he may just have to beg the player to sate his lust. [Prometheus]Bugfixes & Balance Patches
Ares:
In the scenes for taking Ares for a walk, he should now properly serve as a combat companion.Chris
: The correct (naked) icon of Chris in his breeder form should now be shown in Chris’s sex menu scenes.Amy:
The code calling up random interactions with other people in the bunker has been changed, and should hopefully run smoother now.Diego: The time between coming up with tricks to play with Diego has been reduced to 6 turns. [Wahn]
Stat Blocks: Over 80 NPCs have had their stat blocks updated (with more to come). This may not be immediately noticeable to players, but should provide some benefit in future.
Biolizardman Brute: These huge and tall lizardmen seem to belong to a tribe in Avalon, and they are now roaming the deepest parts of the forest. With the shade of the forest’s trees, their scales glow mesmerizingly. For now, they can be encountered and fought, with one scene for each outcome.
Auto-Clear: Hopefully conversations with Genevieve, Gwen, Jimmy, Meredith, Otto, Paula, Sylvia, and Vanessa should no longer be skipped for those who have ‘Waits’ disabled.
Alpha: The hybrid offspring of the Thought Eater now has some neat new artwork to his name, showing off his full tentacled body. [Wahn]
Alexandra (‘Good’): Fixed some errant mentions of locations.
Bouncy Succubus
: A new inflatable succubus can be found at the Beach, ready to make you her personal toy.Demon Fox:
Should now allow people to get the ‘loss result’ rather than the ‘submission result’ when throwing the fight or losing.Batcubus: A typo in the batcubus scenes has been fixed.
Alexandra: You can now dominate the Doberman bitch to gain her as a library npc without having to fuck her. This way, even people who have no interest in her sexually can gain a trusty canine to guard the library (and give birth to Spike, for example).
Void Realm (Abyssal Edge): This is the miracle worker weapon. It is currently the most powerful weapon in FS, but it is quite a hassle to acquire. You see those Null Essences you have been gathering? You need a whole lot of them to restore its broken version (Through Toron at the Hellfire Club) that you can acquire through an event. This is the only way you will be able to weaken some of the encounters. How to find it? Go Beyond The Veil!
Cowbabe-Boots: A small typo in the transformation text has been fixed.
- Click the “export progress” button within the old version of the game
- Once you have the new version open “import progress” (this might take a few minutes)
