Lust Theory Walkthrough for All Achievements and Secrets

Lust Theory Walkthrough for All Achievements and Secrets

A step by step walk through of the game with how to acquire the different achievements and hidden scenes.

Introduction

It is not possible to obtain all of the achievements on one play through, without using saved games to repeat events. On the first play through I’m going to go for the less obvious achievements.

I decided to break the game down into days after the tutorial portion, even though there is no way to keep track of the day number in the game. I put in Save Game prompts for the areas where you will need to play through twice to get an achievement. You could get to the next day, save, then load the save and go through the prompts to get the achievement by going to the Second Play Through Achievements sections. Most of the achievements in the Second Play Through section are the act like an ass type achievements.

As I already had most of the achievements this guide has where you should earn the achievement. For the few achievements that aren’t actually mentioned you should gain them along the way.

The Tutorial

While playing the tutorial part of the game you will not have all of the options available that you will have later.

Before you start playing let the whole main menu video play through to earn the AFK achievement.

The game starts off and you get to select your name and your relationships with the three women in the house, two about your age and an older woman. Only relationships where these people shouldn’t be having sex with each other will make sense in the context of the story.
