Mountaintop.gg

Mountaintop (Mountaintop.gg) was a remote-first independent video game studio founded in 2020 by veterans of Blizzard, Respawn, Riot, and Bungie, led by Oculus co-founder Nate Mitchell. Backed by a Series A led by Andreessen Horowitz (a16z), the studio built Spectre Divide, a free-to-play 3v3 tactical PvP shooter featuring its signature "Duality" two-body mechanic. The game launched in 2024, but the studio wound down and Spectre Divide's online services were shut down in 2025. Mountaintop is a consumer game studio, not an API provider, and publishes no developer API, SDKs, or developer portal, and its public web and support surfaces are now offline. It remains cataloged in the API Evangelist network as an a16z portfolio company with no active API surface.

Mountaintop.gg is profiled on the APIs.io network. Tagged areas include Company, Gaming, Video Games, Game Studio, and Esports.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/mountaintopgg: open an issue to ask a question, or submit a pull request to add artifacts.
