Welcome to the UnderMine closed alpha! We’re very excited to have some real, live players testing the game. This page should answer all of your questions with regards to the alpha, and if it doesn’t we are available in our Discord channel.

Please keep in mind that this is a very early version of UnderMine. You will see unfinished content, placeholder assets, bugs, and other issues we either do or do not know about. We would like your help in reporting these issues so that we can fix them either as part of the alpha, or later in development.

We would also love to hear your feedback on the game. What you like, what you don’t, and what you would like to see added to it.

Thank you for your support.

How long will the alpha run?

The length of the alpha right now is undetermined. Our estimate as of this writing is to run the alpha for around three weeks and end it somewhere between Christmas and New Years.

Will UnderMine be updated during the alpha period?

We’re going to monitor the alpha very closely, and if we feel there are things that need to be addressed we will push fixes for them. Otherwise we may just update the alpha with fun new content if we’re up for it.

Can I stream the alpha or upload videos to YouTube?

Yes! Part of this alpha is to raise awareness for UnderMine. You can both stream it and upload videos. Keep in mind that this is a very early version of the game, and if you see things you are not happy with we would prefer you raise those issues with us so that we can address them.

Can I get a key after the 7th?

Unfortunately, no. We are not going to send out keys after the initial batch is released. If you have an issue with receiving or activating your key please contact us on Discord so that we can sort it out.

What should I do if my game crashes?

Please fill out the form that pops up (including your email address!) and click Send. It makes it a lot easier to fix these problems when we have as much information as possible.

How can I get in touch with you?

You can message us on Discord. Email us. Or send us a DM on Twitter.

I love UnderMine! How can I support it further?

By participating in the alpha you are already doing us a huge service. You can also wishlist the game on the Steam store. Follow us on Twitter, Twitch, or join us in Discord. Thank you very much for your support.
