Young Justice: Legacy was officially delisted from Steam on May 24, 2017. That means you can’t buy it directly from the Steam store anymore. The removal was due to expired licensing agreements.

If you bought the game before that date, it will still be in your library and you can download and play it as normal. But what about people who never owned it?

Even though the game is gone from the Steam store, Steam’s old gift system makes it possible to still add it to your account. Here’s how it works:

Before the game was delisted, some players bought extra copies as Steam “gift” items.

Gift copies stay in the owner’s Steam inventory until they are activated on their own account or sent to someone else.

When you receive a gift copy and accept it, the game is added to your Steam library exactly like a normal purchase, even if the game is delisted.

Option 1: Third party websites it will cost around $500-600 USD (as of 2025)

Option 2: Track the individual owners of the steam gifts using certain websites and try to strike a deal (usually you would pay with TF2 Mann Co. Supply Crate Keys)

If you have trouble finding trusted third party websites or need help finding an owner of a young justice steam gift, add me on steam and I can help you out.

Once you get the Young Justice steam gift in your steam inventory, you can click "Add to Library". Once you click that button, the game will be permanently tied to your account and will act just like any other owned title.

There are no Steam Keys for this game, only way to get the game is through steam gifts

Once all remaining gift copies are gone, it will be impossible to buy the game on Steam.

There are currently 50+ copies left in existence (as of 2025).

Over time, fewer copies will be in circulation because people inevitably activate these gifts.

less copies in circulation = higher price. The longer you wait the more you will pay.

In the game folder find steam_api config file.

Edit the file, replacing the list of DLC 1-10 with this:

DLC001=0000264996
DLC002=0000264995
DLC003=0000264994
DLC004=0000264993
DLC005=0000264992
DLC006=0000264991
DLC007=0000264990
DLC008=0000000000
DLC009=0000000000
DLC010=0000000000

And that's it. You will now have all the DLC


There is still a way to get the DLC officially registered and activated on your steam account today. It involves finding people who own steam gift copies of the DLC and then trading with them.

This will cost you a lot of money, but more importantly, a lot of time. I was able to find all the DLC, and activate it on my account, but I can tell you from experience it is not worth the effort at all.

If you are genuinly interested in how to officially obtain the DLC on your steam account, I can connect you with the owners of tradeable DLCs. Most of these people will overcharge you or just simply not sell because they are also collectors themselves.

I highly suggest proceeding with option 1.

1) If you haven't seen the TV show, I recommend to only watch the first 2 seasons. The rest is complete garbage

2) The game is canon and takes place between seasons 1 and 2

3) Diorama and Journal locations are credit to "xTMx Vovtek" on True Achievements website.

4) There is no existing data base of the costumes online so I made a youtube video to keep as recorded history: https://youtu.be/gxvm9WcjQVo?si=hMBkUqsb8IrwZEyf
