Frequently Asked Questions

Are there micro-transactions?
No, there are no micro-transactions in ultimateXnova. It is completely free to register and play the game on our servers.
What is NextGen UI?
NextGen UI is our brand new user interface with a focus on mobile optimization and a beautiful new design. Don’t worry, you can still use old themes such as “Galaxy of Wars”, although they might be restricted in terms of new features that rely on visuals.
I want to have my own server, how do I create one?
If you have a webserver and the technical knowledge, you can download the latest release free of charge and use the automatic installer to install the game on your own server.
Alternatively, we can set it up for you or even host your game on our servers for a fee.
What happened to 2moons?
While 2moons is the base of ultimateXnova, the project development has stopped a few years ago. It was then further developed as SteemNova, on which this project is based on. We are aiming to fix a lot of bugs and create a completely new user experience.
Can I upgrade from 2moons?
Upgrading from 2moons can be fairly complicated and requires a lot of technical knowledge, but it is possible. Make sure to make backups of your game and your database as you will experience a lot of errors due to changes of the database structure.
Can I upgrade from SteemNova?
Upgrading from the latest version of SteemNova is fairly straightforward. You can run the installer to upgrade the database. Make sure to always backup your game files and database before upgrading.
