How To Install ARK: Survival Ascended Mods on Xbox

Firstly, select the Multiplayer option at the main menu to find the Mods List.
Clicking on this will take you to the mods list menu, where you can see all the mods ready to install on your ASA game server.
When you click on a mod you want, it’ll take you to its info page. There, you will find info on the mod and in the top-right, you can click “Install” to add that mod.
Once the download is done, head back to make a new game or server.
In that, go to the Mod Settings tab at the top.
You’ll see any active mods there, but since it’s a new game, there won’t be any. Switch over to Available Mods, and you’ll find the ones you just downloaded.
Click on the mod you want, then hit the “Active Mod” button at the bottom.
Now your mod appears with an “A” at the start of its name, showing it’s live on the game/server.

That’s it! Your favorite mod is now kicking on your ASA Xbox server.
