TEN MAPS. PLENTY OF BAD COMPANY.
Every place has its monsters.
Explore ten chapters with their own enemies, hazards and bosses. Learn the tells. Find your opening. Try not to become part of the scenery.
THE BONE COLOSSUS Not here to make friends.
Find your kind of strange.
Discover 45 heroes with their own traits and ultimates. Bring a familiar companion to grow alongside you, gather gems or get you out of trouble.
Rewrite your build.
Choose Omens that change the rules of a run. Discover rare inscriptions that change how your weapons behave. There’s always another combination to try.
Wake the bigger monsters.
Climb through Nightmare to Nightmare+, where bosses reveal their full phases and attacks. Beat them to earn new playable heroes.
Still hungry? There’s Endless, daily challenges and the Gauntlet boss rush to unlock, too.

On the results screen, tap the quill button between Retry and To the Book. You can leave a rating, pick tags, or write a note.

NOTES IN THE MARGIN
Before you wander in.
Do I need to register on this website?+
No extra website account is needed. Apple handles TestFlight enrollment; Google handles group membership and Android test enrollment. This page doesn’t collect email addresses or keep a separate tester list.
Why does Android have two steps?+
The Google Group makes your account eligible for the closed test. Joining the Google Play test is a separate opt-in. Complete both with the same Google account you use on your Android device.
The Android test says I don’t have access.+
If Google Groups shows a permission message, sign in to your Google account first. Check that you’ve joined the Mythspire tester group, then check the Google account shown on the test page. It must match your group membership. Try again shortly if you’ve just joined. Google Play also checks device and regional availability. If you’re still stuck, email us.
Can I sign up for Steam yet?+
Not yet. Steam is coming soon, and there’s no Steam signup or email waitlist on this page at the moment. The access link will appear here when it’s available.
