Avalon Adult Game Download Overview

Avalon is a third-person novel that orbits around two main characters; Avalon and Byron. When Avalon has a falling out with her mother, she moves in with her adopted Uncle Byron. As they continue to learn about each other’s deep and disturbing traumas, a romance begins to blossom. They lean on each other, and their friends, as they both continue to heal.

In Avalon, you will be given the option of four paths; Dallas is Avalon’s best friend and an absolute wildcard! She’s tough and flirtatious. Octavia is a mysterious new friend with a cunning intellect and a goofy sense of humor. Both paths have the option to split off into either a Polygamy Route or a Monogamy Route. The choice is yours!​

v7.11 Hotfix 2
I worked my tail off the last several days rebuilding the Gallery and Act Select so I could get the Unlock feature to function properly. I have tested this build thoroughly myself and I’ve had others test it as well. It absolutely should work.
If there are any errors, however, please let me know and I’ll get them fixed up for the Bonus Act release. I want to sincerely apologize again for releasing a version with a feature that didn’t work.
Once again, the password to unlock everything: megalodong

– Final Dallas Poly scene now shows if you’re playing from the start of the game.
– Added an Unlock feature so you can unlock all content with a password.
– Locked the Mono Scenes Button. Unlocks after you finish Act 7.
– Minor aesthetic changes to the menus.
– Minor grammatical and spelling fixes.

(PLEASE NOTE: The lock content feature does not currently function properly. This will be fixed in the next update.)

The password to unlock everything is:


The Final release of Act 7 is here! I appreciate everyone being patient with me while I put together this last piece of Act 7. Let’s go through the additions.
There are a total of four new scenes, one for each path. And each one contains a sex scene sequence.
On the main menu is a new ‘Mono’ button that will allow you to watch all the mono scenes. In order to watch the Poly scenes, however, you will have to play through the Poly paths. I recommend using the Act Selector if your saves are corrupt.
Without further ado, please enjoy the completed story of Avalon!


Bug Fix Release:

  • Fixed mono path jumping to the end in the middle of the act.
  • Fixed Gallery Reply for final lewd scene
  • Fixed two minor grammatical errors.
  • Created an error where it’s hard to see the Change Relationship option at the main menu. Will be fixed upon next release.

  • Over 10 new scenes.

v 5.6


This is a really big update. If you were waiting on playing Avalon until there was a decent amount of content, now is the time to play. This is a great point at which to give it a playthrough. There’s plenty of fun content now and some excellent naughty scenes.

We’ve had difficulty with saves in the past. So with the help of a professional coder, we’ve added an ACT SELECT to help alleviate this problem. Once you finish an Act, the proceeding Act will be unlocked in the ACT SELECT menu. Please thank OscarSix for this addition!

I also had a GALLERY implemented so once you’ve seen a scene, it will unlock in the GALLERY. Remember, there are four paths. So to unlock all the naughty scenes, you’ll have to play through them all. Each path has additional information about the story but the Mono Paths have considerably less content as of this release than the Polyamorous paths. Please thank OscarSix for the addition of the GALLERY.

We’ve also implemented a SAVE GAME NAME feature. It’s a little tricky; when you go into the Save Game Menu, type in what you want to name it, and then click the slot you want to save on. Please thank OscarSix for the SAVE GAME NAME feature.

v .5.4 – Release Date May 5th, 2020

I found a new method of compression that greatly reduces file size without compromising quality. You’ll find this release to be much smaller in size. (Credit to Recreation from Bad Memories for the assist!)

RENAME BYRON – That’s right, you can now name Byron anything you want! If you load the game, you’ll find his name is now [player_name]. You can combat this by either starting a new game or by starting the newly released content. There is an option just as you start Act 5 – Afternoon that will allow you to rename him. (Credit to Sir Dammed from Polarity and Radiant for helping with the code!)

We’ve altered the Mono path for Dallas. She was originally going to pursue Evans but due to popular demand, she’s going to pursue… someone else. 😉 So we’ve altered the scene with Penny at Dallas’s house to reflect this change.

Scenes –

Byron and Ava Couch Cuddle

Penny meets Gladstone

Avalon Video Calls

Avalon visits Sharol

Dallas, Avalon and Penny Salon (Dallas Path)

Penny Quits (Octavia – Mono Path)

Xianne’s Dreaming of Sun Mei

I hope you all enjoy this release. The next one is going to take a bit longer than usual because there’s going to be some exciting scenes and I want to make sure there is plenty of content. But I’ll keep you guys updated, I promise!

Main Scenes:

Penny’s Morning Routine​

Avalon’s Therapy Session​

Special thanks to Praenuntius and TrulyDemented for their hard work in hunting down grammatical and spelling errors! We’ll see a considerable reduction in errors for all Acts. Thanks, guys!

We’ve started our Patreon page and opened up Discord to the public. Come visit us!

Myrabelle’s first Mini-Episode has been released to Patrons. The Time Collector, a scrapped project from Lockheart, has also been released to Patrons. See our Patreon page for details.

Added a short tutorial to the beginning of the game to explain how the choices work. If you’ve played V.4, there is nothing new.


Included in this update is Act 4.

I considered the main complaints from the community. In this release, we focused on three major things.

  1. Choices – We’ve added choices and two additional paths to Avalon. The two new paths are Polygamy and Monogamy. Currently, monogamy just cuts out any sexual content between Avalon and Dallas or Octavia. This will be a more realized path in Act 5. Polygamy is how the game was originally designed to be played. Avalon is now a Visual Novel instead of a Kinetic Novel.
  2. Sexual Content – We’ve added several new sex scenes. There is now a decent amount of sexual content.
  3. Eyes – I know the eyes don’t sit right in some of the pictures so I went back through and re-rendered quite a few scenes. We’ll see much less of that problem


Reworked version of Act 3.
Removed Dentist Scene
Changed the personality for Penny.


  • Two new scenes with Dallas
  • Two new scenes with Octavia
  • One new scene with Penny
  • One sexy night scene with Avalon and Byron

Included are the first three Acts.
