Character Info
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.

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.

DoggoMod 1.0
Thanks to everyone for your work getting us the game.. so enjoy the “DogMod 1.0” zip that I added to the post.
Edited.. fixed the minor_scenes.rpy line 1020 from “if sisO.exhibitionist:” To “if sisO.exhib:”
This mod’s main feature is a MAJOR change in the “Normal” difficulty mode. What is does is it crippled the resistance modifier. The stat will show a (0) and will continue to show that so you can see you are not gaining any resistance. Another main feature is the tweaking of chances of RNG events to make it more likely to occur. Also, the money and serum systems are ‘rebalanced’ in your favor to give you more time to dole out serums and to buy serums if needed. The goal of this mod is to make it easier for you and reduce the grind so you can rack up a sex score that would make a prostitute jealous. And there’s quite a few cultural references thrown in. :p

To install, unzip and put all **.rpa files in the “Lab_Rats-1.0-all\game” folder and overwrite.

I provided a backup folder of the original files so you don’t have to worry. All you have to do is unzip and put in the /game folder and your Lab Rats are back to “Normal”. But why?? O.O

I included a “how to” file and for those who are curious, I added 2 more documents.. One is a detailed log of what I did to change variables and where. The second is about the Random Events and how I modded it.

(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


v1.0 won’t be the end of Lab Rats 1. I have plans to keep development going for a while longer, both to add a little new content and to knock down any bugs if (when) they show up.

lab-rats-vrenGreat game. Lots of content, lots of teasing, solid non-ridiculous sounding writing. Well-proofed. Highly recommend for people who like games with interesting gameplay, without needing two hands. Way less ridiculously convoluted and complicated than the sequel.
