Short answer
The useful part first.
The official website is paxautocratica.com—with no hyphen. The developer has explicitly warned that pax-autocratica.com is not affiliated with Multiverse and identified it as fraudulent.
Official vs. lookalike domain
Official
paxautocratica.com
No hyphen. This is the domain named in the developer’s warning and linked here as the official site.
Not affiliated
pax-autocratica.com
Includes a hyphen. The official warning says this site is not affiliated with Multiverse.
The safest way to buy
Use the official Steam store page linked in the source rail. Confirm the app name, developer, and Steam app ID 1067360 before purchasing or activating anything.
If you already used the lookalike
- Do not enter any more login, payment, wallet, or activation information.
- Change any reused password through the real service—not through a link from the lookalike site.
- Review the affected account and payment method for unfamiliar activity.
- Contact the developer through the official site if the page claimed to represent Multiverse.
Why a search result is not enough
Lookalike domains can use the correct game name, screenshots, or search-friendly text. Check the full hostname before trusting a page, especially when it asks for credentials, payment, downloads, or a Steam key.
