Overview:
It's our first game made with Unreal Engine 5!
For the past year, we were hard at work to remake "Lust Theory" in Unreal and now we
think it's a great time to show everyone what we've have created.
we remade everything from scratch.
In this first release, you can explore the house and our new suburbs map, complete quests, talk and interact with 2 different female characters! This is only the beginning of something we are putting our heart and soul into. We will continue building the world of Unreal Lust Theory, one step at a time and your support would be much appreciated!
As you can see in the preview, we are looking at the map and characters from our original game and remaking them to be, not only better, but more fulfilled then the originals. The map is larger and you can now explore the space where you live in. In future updates, we will add the city where you can go to the mall, some shops, the college, etc.
It will receive monthly updates so you can expect more animations, dialogues, naughty scenes, quests, new gammeplay elements, new characters and much more. Keep in mind that everything we showed you with this version 0.1 will only be expanded further.

v0.3.7.0.1
After two weeks of Unreal Lust Theory v0.3.6, it’s time for something new. It’s a small patch, but we hope you’ll enjoy it.
First off, we’re keeping the Halloween theme for one more week. Some of you asked us to leave it on Steam since you hadn’t had a chance to play it yet. So we listened, and Halloween will stay for now. When we remove it, certain quests like the Halloween Basement Key may not activate with a date change because the basement will already be unlocked. But we'll see.
Some of you have also asked for FSR and DLSS. We gave it our best shot, and for now, we’ve implemented AMD FSR 3.1 into the game. If your PC meets the requirements, you can enable it in Graphic Settings and give it a try. We’re also exploring the possibility of adding DLSS, but it’s more complex than it sounds—it’s not just a plugin. Still, we’re listening to your feedback, and we’ll see what we can do.
Last week, we held a poll on our Patreon page. We promised a spicy scene with the MC and the two girls with the most votes. We had a total of 1,795 total votes, but when adjusted by voting power, here are the final results:
We also wanted to update you on our progress. We have a new animator working on scenes with Sophie, and he’s doing a fantastic job! We’re excited to see what he has in store for her and us.
Without further ado, here’s the update list:
New Content:
v0.3.6
Introducing the Commands Menu: Though still in a basic form, the Commands Menu will eventually play a key role in Story Mode, making future updates easier to manage.
Currently, you can activate it with TAB (or customize to your liking) and close it the same way, by clicking outside the menu (don't click on buttons) and pressing TAB, or by clicking the "X".
Here’s what it currently offers:
We are so excited to bring you this Unreal Lust Theory v0.3.5 update! After a long wait, we’ve finally managed to create our very own Main Menu and fully developed product. This will make it much easier to handle and optimize across all systems. We hope you’ll enjoy it and share your feedback with us.
Along with the new Main Menu, we have another surprise for you. We've been secretly working on Ellie. She’s not quite ready yet, and we’ve encountered some issues with her design. The plan is to release her to you now so you can provide comments and help us improve her appearance. We'll handle the technical issues that aren’t visible. This is the best approach because it allows us to make adjustments while continuing to develop her. Ellie is being released for testing purposes only. Sophie will also be released, but our current priority is to finalize Ellie and then move on to Sophie.
Thanks to your support, we were able to hire another animator, who will be joining the team next month. He’ll start working on Sophie, and we’ll provide more updates once he begins.
Now, let’s get back to the details of this update. Here’s what you can expect:
30 new animations (6 sex bed animations and 24 cum animations)
A new user interface, allowing you to change poses with a button, making it much simpler
The option to hide the MC if you want
15 new unique gallery summer wallpapers that you can't get anywhere else!
A new WEB PAGE where you can see news about our game (old and new)
Improved UI when interacting with girls
5 new clothing items
1 new clothing socket (chest)
Steam community items are currently under review, and we are waiting for the green light to publish them. These will be a bonus with this update:
5 collectible badges plus a foil badge
5 trading cards
7 really cool emoticons that we hope you'll use
3 static profile backgrounds
6 amazing animated profile backgrounds
v0.3.3.1
Fixed a critical bug that caused the game to crash when opening settings in drone mode.
Adjusted skin wetness and speed for better realism.
AZERTY keyboard rebinding now works perfectly.
Resolved several animation clipping issues.
v0.3.3
New Features:
Cum in Scenes: Finally, you can now use Cum in the scenes! This highly requested feature is now available, it's still work in progress but we are happy with it atm.
Clothing in Scenes: Option to change clothing in the scenes. There are 11 new pieces for you to try out.

We’ve implemented a performance update.

v0.3
N/A
v0.2
For everyone who doesn't know, we released version 0.1 few months ago and got ton of feedback. Basically, from then to this day we worked on v0.2, taking your feedback into consideration.
We had to remake Megan and MC in Blender because in v0.1 their quality wasn't that good, at least not how we and you hoped for.
Also, now we optimized everything!
We prepared for you a small version but with more details and better animations, because once again, we have new characters! House is game ready and from now on we will start preparing the outside area.
Jessica is also being remade in Blender for the next update that will come out sometime around Christmas. In the next update, you can expect her and even more animations, dialogue options, etc... We will give our best to deliver what you suggest in the comments below or on Discord.
