Cracking: The Second Strain
by Cr4ck

TL;DR: This game is about a virus that turns people into voluptuous sex zombies against their will.

You're in control of a highly sophisticated virus capable of turning any man into a sex starved beast and any woman into a cock hungry slut within a matter of seconds. You will start of small, corrupting anything you can get your hands on but as your horde of oversexed servants grow you will move onto taking over small towns, cities, countries, continents and eventually the entire world and repopulate it with nothing but mindless slaves who can think of nothing but sex. The game mostly focuses on transforming other people around you against their will but does have some self transformation as well.

This game is a spinoff of the story "Cracking" over on CHYOA. If you would like to read it then head over here for more mass corruption goodness.

Currently working on:

Adding new locations to chapter 2

Adding alternate routes and improving the existing ones in chapter 2

Can include spoilers!

Chapter 1

Go through the intro

Go through gas station to regain your strength

Go to the hotel via the park

Enter the hotel room and find the viagra to learn aphrodisiac

Go to the kitchen and infect the food

Go to the park and infect the woman using the spores and the aphrodisiac (NOT the normal "infect" ability)

Go back to the hotel and go to the dining room to infect everyone in there

Proceed to fully conquer the hotel and claim it as HQ

End of chapter 1

Chapter 2




New Imagery:

  • All non-generic locations in town now have images

New/Updated Scenes: 

  • Miller Residence alternative route (Requires trojan) 

Bug Fixes:

  •  Fixed a bug that prevented the numbers of symbiotes in the horde from ever raising above 0



New Imagery:

  • Added imagery to multiple of the locations in chapter two to bring the town more alive. Just like in chapter one these are placeholders that eventually will be replaced by commissioned art

New/Updated Scenes: 

  • Rewritten several house intros so to allow the player to have some idea of the people occupying each house (Referring to the common houses found throughout the town, not notable ones like the fire station for example)

Bug Fixes:

  • Fixed a bug causing the number of infected to occasionally be reset back to 0



New Imagery:

  • Imagery depicting a pair of test subjects has been added to the introduction

New/Updated Scenes: 

  • Changed the structure of the Miller residence

Other Changes:

  • Traces of the fertile woman's scent can now be found all over town until she's been captured and converted

Bug Fixes:

  • Fixed a bug causing the number of infected to show up as "$infected" after hibernating



New/Updated Scenes:

  • Anderson Residence alternative route (Requires hyper spores) 
  • Updated and rewrote the default route for the Anderson Residence to be more extensive

Bug Fixes:

  • Fixed a bug causing the player to sometimes get stuck in the “tips and rumors” tab when talking to Sarah 
  • Fixed a bug that allowed the oil to be acquired multiple times in a single playthrough



New Imagery:

  • "Matriarch" in the "Cracked Types" tab (and in the last scenes of chapter 2)

New/Unlocked Scenes:

  • Town square orgy
  • Sarah sex scene
  • Chapter 2 ending sex scene (optional)

Other Changes:

  • New unit: The Matriarch


Version 0.2.0 now allows for a full proper play through of all of chapter 1 as well as chapter 2 however this doesn't mean that chapter 2 is completely done, only the "shell" has been completed. I'm still looking to implement improvements to the existing scenes, multiple paths and ways to infect various locations, a couple more mechanics and of course more images.

Edit: I accidentally forgot to update the version watermark in the game so it will still say "0.1.24" on the sidebar, however this is strictly visual and shouldn't impact the game play at all.



New/Unlocked Locations:

  • The Town Council

Other Changes:

  • The structure of the Anderson's residence has been changed for better flow as sort of an "experiment". I'm planning on changing all buildings to use this new structure over time as it allows me to easily add multiple ways of infecting each building as well as integrate a few new mechanics I've been working on

Bug Fixes:

  • Images should now always load in at the correct size



New/Unlocked Locations:

  • The Atrium
  • Rewrote the scene in the Zimmer residence to be more extensive

Other Changes:

  • The "name scan" ability now gets automatically picked up in the introduction to chapter 2 rather than once you infect the lab
  • I've started updating the naming structure in the game to give better clarity to the player who's talking during dialogue. Before humans were either tagged as their name, their profession or simply as "Man 1" or "Woman 2" etc. Now all future humans will be tagged as "Name (Title)". For example where before it would either say:

    Kate: "Dialogue text" (If you knew the name)
    Daughter: "Dialogue text" (If you didn't know the name)

    Now it will say:

    Kate (Daughter): "Dialogue text"

    And since the name scan ability is now given at the start of chapter two, no humans after that point should be unknown to the player. All dialogues have not been updated yet though and I will continue updating the old ones in the background over the coming updates.



New Imagery:

  • The Broodmother imagery in the "Cracked Types" tab has been updated

Other Changes:

  • The Broodmother biology has been altered to go along with the new art, as such multiple areas and descriptions have been updated in accordance with these changes

Bug Fixes:

  • The police station will now be properly marked as infected after infiltrating the building and corrupting everyone inside



New Imagery:

  • "Broodmother" in the "Cracked Types" tab

New/Unlocked Locations:

  • Town Hall - Small office
  • Town Hall - Large office

(Both require you to have dealt with the police first)

Other Changes:

  • Removed the "legacy sex scenes" tab as all scenes have been properly rewritten back into the game now
  • "Humans infected" has been changed to "Infected humans"
  • Humans that's been infected through buildings will now also increase the amount of "Infected humans", not just the total amount of infected. Cracked birthed by Broodmothers will still not increase the "Infected humans" however.

Bug Fixes:

  • The upgrades requiring Oil, Wax and Booze should now be displayed properly on the laboratory screen (They were inverse before)



 New/Unlocked Locations:

  • The Cinema

Other Changes:

  • Reduced the Forcer's horde strength to 10 from 3
  • Reduced the Broodmother's horde strength from 10 to 5
  • The "Horde Overview" tab is now unlocked at the start of chapter two. There you can see a detailed breakdown of all the units currently in your horde as well as their combined strength.
  • "Humans infected" is now it's own stat and is not increased by infected birthed by your Broodmothers. It's ONLY increased by actually infecting humans yourself.



New/Unlocked Locations:

  • Police station part 3 (Final)

Other Changes:

  • The Mansion has been replaced with a Cinema in preparation for 0.1.20

Bug Fixes:

  • The Police Station will no longer be incorrectly marked as completed in the "town overview" screen when the radio station has been infected.



New Imagery:
  • "Forcer" in the "Cracked Types" tab
  • You can now see how you look in the "Status" tab

New/Unlocked Locations:

  • Police station part 2

Other Changes:

  • The Forcers have changed a bit in design to better fit the imagery now added to the story, as such a large amount of scenes and descriptions have been changed to accommodate for these differences. (Also if you find any that I've forgotten to change then let me know ASAP as I might've missed one or two :S)



New/Unlocked Locations:
  • The Post Office (Stealth path)

Other Changes: 

  • You now get a summarization of how much your horde has grown each time you hibernate so you don't need to manually add up all the numbers from your infected buildings. This makes it a lot easier to gauge your progress especially once you've infected a large number of buildings later in the chapter.



New Imagery:
  • "Infected/Common Cracked" in the "Cracked Types" tab

New/Unlocked Locations:

  • Police station part 1

Other Changes: 

  • The Symbiote has been added as one of the units in the "Cracked Types" tab



New/Unlocked Locations:
  • The School Gymnasium (Essentially part 2 of the school)

Other Changes:

  • All upgrades and quest paths will now be done directly from the lab rather than the “Tips/Upgrades” section to prevent quest overlapping. This allows for more freedom in choosing which building to infect next and should also fix the bugs that occured for example when trying to infect the church before the radio tower
  • The " Tips/Upgrades " tab has been renamed to "Tips and rumors" to accommodate for the change
  • Once the Broomdmother gets unlocked new trivia related to the unit type will be available from Sarah

Bug Fixes:

  • The trivia tab should now work properly again



New/Unlocked Locations:
  • The School
  • The Post Office (Alternate path)

 New Abilities:

  • Trojan



New Imagery:
  • "Normal human" in the "Cracked Types" tab
New/Unlocked Locations:
  • The Post Office
  • The Pub
  • Woman Interrogation
New Unit Type: 
  • Broodmother - Broodmothers have been added as passive income bonuses during chapter 2. In chapter 3 the management of allocating  breeding and such will return like it was in version 0.1.6 of the game.
Bug fixes:
  • Fixed the “Interrogate woman” option being visible from the start in the lab but removed after infecting the hospital, is now the other way around (Messed up an if statement). 



New/Unlocked Locations:
  • The Smith Residence
  • The Hospital 
Bug fixes:
  • Fixed a bug that prevented Sarah from teaching you possession, making you unable to access the last parts of the church quest line.
  • Fixed a bug that for some strange reason occasionally closed the browser.



New/Unlocked Locations:
  • The Lewis Residence
  • The Johnson Residence
  • The Abandoned House
  • The Church
New Abilities:
  • (Re-implemented) Possession



New/Unlocked Locations:
  • The Mall
  • The Radio Station (Take over)
  • The Town Hall
Other Changes:
  • Reworked the fast travel system, you now have access to fast travel to all buildings at the start of chapter two (you still won't be able to enter all of them immediately though) and their descriptions have been replaced with easier to read "information cards".



New/Unlocked Locations:
  • The Library
  • The Gym
  • The Fire Station
Other Changes:
  • The "exhausted" mechanic has been streamlined to better notify the player if they are exhausted or not before they enter a building.
  • Minor bug fixing and grammar corrections.



New/Unlocked Locations:

  • The Hairdressers

The Sushi Bar

  • The Radio Station
  • The Veteran's Residence

New Abilities:

  • (Re-implemented) Shift

@Decapitare0 A lot of games on this site are only text. Heck, I think they may be the majority.

Interesting game, shows promise.  Here's hoping for quite a bit more pregnancy content ;-).

Really fun start to a game!  A bit linear to start but not entirely, and can easily see the potential of where the game will grow.  Props :D
