The game centers around the corruption and seduction of the women that you, the player, associate with over the course of a summer term working as a lab assistant.

You – A third year chemical engineering student, brought onto the lab team to help keep the equipment working.
Nora – The lab director. Science is her passion, and she runs her small lab with enthusiasm.
Stephanie – A graduate student and fellow lab assistant. She has been Nora’s right hand girl for years.
Mom – Your mother. Without your father she works long hours to make sure you and your sister can both earn a university education.
Lily – Your younger sister. She also goes to the same university for History, but unlike you has the summer off.
Alexia – A classmate from last semester. She seems to be interested in seeing you more over the summer.

1- Extract to desired location.
2- Click on “Lab Rats.exe” to start playing.


– Added two new difficulty settings that make the game easier, increase the number of days available, and limit what endings are available.
– Added option in info notebook to skip to the end of the game. Skipping also gives the option to have sex with each girl as many times as possible.
– Added pregnancy score counter in the notebook so you know how close you are to getting someone pregnant.
– Added new minor scene for Mom in the shower.
– Added new minor scene for Lily in the shower.
– Added new dialogue branches when a girl is off her birth control but you still finish inside of her.
– Added new dialogue sections for Free Use and Exhibitionist training in all minor scenes.

– Sending Mom to work in a slutty outfit with exhibitionist now only results in her gangbanging the office if she is also trained as freeuse.
– Made it more likely for you to find Lily in her room, rather than it being empty.
– Made it more likely for you Lily to be stood up for a date.
– Made it more likely for Nora to invite you to the office party.
– Made it more likely for you to run into either Mom or Lily at night.
– Made it more likely for Nora to invite you over to help her move furnature on the weekend if you text.
– Made it more likely for Nora to come over to your place to help you study on the weekend if you text.

– Fixed error with training resistance reduction that would increase resistance if a girl was trained with purple serum instead of the reverse.
– Smoothed edges for several images used in the pregnant harem ending.
– Fixed a ton of spelling mistakes.

(day = 1 would set it to day 1, day 43 would set it to day 43 etc)
(0, 1, 2 for morning/afternoon/night)



if you want the pregnant
momO.preg_score = 100
sisO.preg_score = 100
noraO.preg_score = 100
stephO.preg_score = 100
alexO.preg_score = 100

Difficulty Settings:

The standard game difficulty is now called “Normal” and is joined by “Easy” and “Sandbox”. Easy is much like the base game, but turns up the influence gain, turns down resistance gain, and starts you with a little extra money. Sandbox does the same, but gives you even more money to start with and extends the game to last 360 days instead of the normal 120.

To give a small incentive to play the normal version of the game (which should be the most fun to play if I balance everything correctly) the endings you can receive on Sandbox and Easy are limited. You receive no special endings at all on Sandbox, and on Easy you cannot receive any of the multi girl endings.

Please wait...

He got downvoted a lot, but you really do have to save scum shamelessly to get ANYWHERE in this game due to how RNG-based all the events are (just using rollback doesn’t reset the random number generator and will just produce the same event again) and there aren’t any actual… Read more »
