This game is still under active development.
Be aware that any unused content you find may become used or removed in the future. Please only add things to the article that are unlikely to ever be used, or went unused for some time. If they do get used, please remove them from the page and specify in the edit summary!
This article is a work in progress.
...Well, all the articles here are, in a way. But this one moreso, and the article may contain incomplete information and editor's notes.
To do:
  • Rewrite this whole page. The website content needs to be separated from the content that was actually integrated into the engine at one point, right now it's a disorganized mess.
  • Document the recently discovered 2007 build of the game engine, as well as the 2008 build.
    • We could also maybe document the crash canyon build that was released during the 2013 Virtual BLOXcon.

Roblox is an online game creation platform that allows users to design their own games and play a wide variety of different types of games created by all kinds of users.

Despite having a notoriously toxic status in other online communities, the game engine itself is actually an impressive feat, featuring very powerful and flexible tools that allow for development across all sorts of hardware.

As the game engine itself is constantly receiving new features and content, this article will be focused on features and content that have been removed from the game engine over the years, as well as the really old builds that have been hard to come by.

Also, note that games created in the engine can use the textures and sounds listed here, therefore while unused in the CoreScripts and other official game engine code, they may be used in Roblox games.

Unused Graphics

While these graphics aren't used by the actual developers of Roblox, anyone can use them in their games. When the game received a massive UI redo, a bunch of graphics from before the UI redo remained in the game's files.


Although not so significant, the game used to have a second currency called Tickets (Tix for short) that had been around since 2007. The currency was removed in 2016, leaving this texture unused.


An earlier version of the Robux currency icon, which was replaced in 2019. Since then this texture has never been used.


Appears to be an early redesign for what would replace the older icon (seen above) for the Robux currency.

Clb robux 20.png



It seems like the player list icon for Roblox Premium (the membership that replaced Builders Club) was originally going to be a diamond, but it was replaced with a P.


This image is a gray square with rounded corners. It can be assumed that this is a 9-square image, which is used in Roblox development to give objects rounded corners, as up until recently, the GUI engine did not natively support rounded corners. The image was probably going to give the chat box rounded corners when the user is in VR, however, this wasn't used and the chat box is the same as the desktop and mobile chat box, with square corners.

The Roblox logo was included in the game files which was used in a loading screen for about a week during 2014 which replaced the simple loading status text in the middle of the screen. An example of this screen can be seen in videos from the time, for example, this one, This was replaced with a much simpler loading screen, which only included the game's name and its creator.



As mentioned above, from 2014 to July 24, 2017, this spinner was the status indicator that appeared on the loading screen, it had "Loading..." written in the middle of it. It eventually became unused and a spinning Roblox logo took its place.

Unused Microphone Icon

An icon for a microphone exists in the game's files.


Unused Faces

In an effort to phase away from their programmer art style, Roblox tried to propose new cartoony face styles and characters around 2012.
Due to the overwhelmingly negative community feedback, these face styles were scrapped (for the most part at least...), but they still remain uploaded on the catalog. The Sarge, Missy, and Max faces were shown in a post on the ROBLOX Blog.

Hack of April 2012 Faces

These faces were not officially made by Roblox, but were created by players, and released "officially" by the Roblox account during the hack of April 2012. Although the faces have been removed from the Catalog, the image files for them remain.

Face Name Face Image Link Image Description
c: https://www.roblox.com/library/76382977/c-Image It is actually quite terrifying. It stares into your soul, waiting to consume it. Gotta luv dah cutie face c:.
hai guize derp https://www.roblox.com/library/76385103/hai-guize-derp-Image Not as terrifying as c:, but it is still disturbing. (No description available)

Unused Meshes

In Roblox, meshes are models uploaded directly into the game with a specific ID and are usually used for making hats, gears, and other complex 3-D Materials. However, some appear to be completely unused.

Early Character Redesign

This appears to be an early attempt to redesign Roblox's character. The model was codenamed "John", (most likely named after John Shedletsky, the first employee and former creative director of Roblox) and it is fully-modeled. It was placed on the Roblox blog in 2007 with a texture, and the textures were rediscovered on 10/27/2017, leaving the opportunity to create a recreation of the model. For whatever reason, it has a scale that makes it very large. This is a demonstration. The mesh can be found here.

RobloxScreenShot02022016 185001856.png

Using the textures that were uploaded onto the site and fixing the UV maps on the mesh reveals some interesting things, namely that the hair texture was changed before it was uploaded onto the client and site. It's currently unknown if isolated versions of the limbs exist.



At one point, while badges were still in development, they were going to be a full-on customized mesh rather than just a shiny block with a circle-cropped image of whatever you uploaded as the icon on it. This texture seems to have been designed in such a way that it could be easily retextured by the player, however, it's anyone's guess as to what was originally intended by the texture.


Here is a mockup of what it would look like in-game with a badge texture.

Egg Hunts

The annual Egg Hunts usually have some cut content, as do a lot of events, due to the approaching deadlines.

StackingDoll Egg


The StackingDoll Egg is an unused egg for the 2012 Egg Hunt. The model is split into two halves, like a real stacking doll.



There is a texture titled ColoredDotEgg that was created around the time of the 2013 Egg Hunt. The background of the texture hides CommanderVideo from the Bit Trip series..

Friend Egg


The Friend Egg was supposed to be used during the 2014 Egg Hunt. It is unknown how you would have obtained this egg but it might have been obtained by playing with a friend or making friends during the event.

Gross Egg


The Gross Egg was supposed to be used in Egg Hunt 2018 that was cut. It is actually a retexture of the Malicious Egg from Egg Hunt 2014. There are also 2 other retextures of the Malicious Egg: one orange, the other purple. This is one of the few canceled eggs to be put on the catalog.

Inviter Egg


This Egg is the oldest canceled egg (that we have knowledge of) that exists. It was supposed to be used in the 2008 Egg Drop. It can be assumed that this egg was used in the now-defunct Invite a Friend program, where users could email friends invite links to gain an Inviter badge on their profile.



Another Egg meant for the 2018 Egg Hunt, It is unknown which world this egg was supposed to be collected in if this was a randomly spawning egg or an egg that you had to do a quest to obtain. This is one of the few canceled eggs to be put on the catalog.

Mad Egg (Original Version)


This is the early version of the Mad Egg that was used in the 2015 Egg Hunt. This was replaced with a dark red egg with three fancy knives stuffed in the top part.

Battle Egg


An egg meant for the 2013 Egg hunt based on another Roblox game called "Roblox Battle", It might have been a cross-promotion with Roblox Battle.



This egg-shaped box is an early version of the Terrible Gift of Korblox Ancients.

Dragon Scale Egg


Yet another egg meant for 2018, It looks rather unfinished so it was probably cut early and replaced by the Dreggon.

Unused Sounds

snap.wav A sound of a loud snap.

	This script creates sounds which are placed under the character head.
	These sounds are used by the "LocalSound" script.
	To modify this script, copy it to your "StarterPlayer/StarterCharacterScripts" folder keeping the same script name ("Sound").
	The default Sound script loaded for every character will then be replaced with your copy of the script.



	Author: @spotco

	This script runs locally for the player of the given humanoid.

	This script triggers humanoid sound play/pause actions locally.


	The Playing/TimePosition properties of Sound objects bypass FilteringEnabled, so this triggers the sound

	immediately for the player and is replicated to all other players.


	This script is optimized to reduce network traffic through minimizing the amount of property replication.

Debug Information

The game has couple of debugging tools built in which can be enabled and disabled on command.

Key Combination Result Screenshot
Ctrl+Shift+F1-Ctrl+Shift+F7 Shows various things about the game like the physics engine. Can't be interacted with.

F1 shows general information. F2 shows graphics information. F3 shows network information. F4 shows performance information. F5 shows a cutdown version of F4. F6 shows a modified microprofiler that is configured to work with Roblox. F7 shows the 'Performance Stats' (also can be enabled in the game's options).

RBLX ClassicDebug.png
F9 or typing /console into chat Shows the game's Lua script logs, to determine what is going on in the background. Intended for game developers to debug their games online. If you own the game, you can access a Server Logs menu which allows you to type Lua commands while the game is running. RBLX LoggerDebug.png

Interestingly enough, the F1-F7 debug menus are the only remnants remaining of Roblox's legacy hard-coded UI system, from the ages prior to late 2009.
Almost all of the old built-in UI elements have been removed from the engine, in favor of using the publically accessible, Lua player GUIs.
