Privacy
Ninebolt Works. Last updated 22 October 2026.
1. Who we are
Ninebolt Works makes Steelmarrow and runs this site and the network test. For anything in this label, write to [email protected].
2. What we collect
When you hang a ticket: your email, platform, region and the time you agreed. During the test: match results, connection quality, crash reports and basic device specs.
3. Why we collect it
To send test details, to match you with fighters near you and to fix what breaks. Under applicable data protection laws, such as the GDPR, we rely on your consent for emails and on legitimate interest for test telemetry.
4. How long we keep it
Sign-up data is deleted 90 days after the test ends unless you ask to hear about launch. Telemetry is kept for 12 months, then only in aggregate form.
5. Who sees it
Our team and the hosting and email providers we contract with. They process data only on our instructions. We never hand your data to advertisers.
6. Transfers
Test servers run in several regions. When data leaves your region we use contractual safeguards recognised by the relevant data protection laws.
7. Your rights
You can ask to see, correct, export or delete your data, object to processing and withdraw consent at any time. You can also complain to your local supervisory authority.
8. Cookies and local data
This site sets no tracking cookies. It keeps nothing on your device beyond what your browser caches by itself.
Terms
Ninebolt Works. Last updated 22 October 2026.
1. Agreement
By signing up or playing the network test you accept these terms. If you do not accept them, do not take part.
2. Who can join
You must be at least 16, or the age of digital consent where you live, and hold an account on your chosen platform.
3. Test access
Access is personal. Do not share or trade your test key. We may limit places by region and platform.
4. Conduct
No cheats, exploits, bots or harassment. Fight the fighter, not the person. We may remove anyone who breaks this rule.
5. Footage
You may stream and share footage from the test. Please mark it as a test build so nobody mistakes it for the final game.
6. Availability
Servers may go down, matches may drop and progress will be wiped when the test ends. The build is unfinished by design.
7. Ending access
You can leave at any time by deleting the build. We can end the test or your access early with notice on this page.
8. Contact
Questions about these terms go to [email protected].
EULA
End User Licence Agreement for the Steelmarrow network test build.
1. Licence
Ninebolt Works grants you a personal, limited, non-exclusive and revocable licence to install and play the test build during the test window.
2. Restrictions
Do not copy, modify, decompile, reverse engineer or redistribute the build, and do not run tools that change how it plays.
3. Ownership
The build, its fighters, arenas, art, music and code belong to Ninebolt Works. This licence gives you no ownership.
4. Feedback
If you send us ideas or bug reports, we may use them to improve Steelmarrow without owing you anything for it.
5. Updates and data
The build may update itself and send the telemetry described in the Privacy label.
6. Termination
The licence ends when the test ends or if you break this agreement. Delete the build when it does.
7. No warranty
The build is provided as is. To the extent the law allows, Ninebolt Works is not liable for lost progress, crashes or damage arising from the test.
8. Governing terms
Mandatory consumer protections where you live still apply. Nothing here removes them.
Help
Fixes for the most common problems in the test.
1. System needs on PC
Windows 10 or 11, 64-bit. Six-core CPU, 16 GB RAM, a GPU with 8 GB VRAM and 45 GB of SSD space.
2. I did not get an email
Check spam, then sign up again with the same address. A second ticket replaces the first.
3. Matchmaking is slow
Widen the connection range in Settings, Network. Late nights in smaller regions run thin.
4. The game crashed
Leave the crash reporter on. It sends the log to us, and the log is what we fix from.
5. Controllers and sticks
Pads and arcade sticks on all platforms. Remap every input in Settings, Controls.
6. Accessibility
Subtitles with speaker names, gauges with shape cues as well as colour, hold instead of mash, and adjustable screen shake.
7. Contact
Write to [email protected] with your platform and the time it happened.
