Hydroneer: Journey to Volcalidus

Overview

Hydroneer: Journey to Volcalidus is a 2024 Adventure game developed by Foulball Hangover, who self-published it. On Steam it has gathered 242 player reviews, 79% of them positive, which counts as a mostly positive reception among indie titles in the Adventure category. The game is available on windows, and launched at $10. As a self-published Adventure project, Hydroneer: Journey to Volcalidus sits among the independent releases indielist tracks where the developer Foulball Hangover retained both creative and commercial control, a path many indie studios weigh against signing with a publisher. indielist's white-box model estimates its lifetime sales at roughly 8,000 to 19,000 units, with the full Boxleiter factor breakdown shown on this page rather than a single black-box figure. Within indielist's catalog of indie games mapped to their studios, publishers, and funding, Hydroneer: Journey to Volcalidus can be compared against similar Adventure titles and benchmarked on review counts and estimated sales.

indielist estimates lifetime unit sales for Hydroneer: Journey to Volcalidus at roughly 8,000 to 19,000 copies, with a median around 13,000, derived from its 242 Steam reviews using a multi-factor Boxleiter model (version v1.0). That median maps to approximately $76K in net revenue after Steam's 30% cut, regional pricing, and refunds. Unlike black-box trackers, the full calculation is shown on this page: a base review-to-sales multiplier is adjusted for release year, launch price, review sentiment, studio size, and genre, and every adjustment is listed so developers, publishers, and investors can audit exactly how the figure was reached. The range itself reflects genuine uncertainty — review-to-sales ratios vary widely between games — so indielist publishes a low, median, and high band rather than a false-precision single number, and treats free-to-play, heavily discounted, and bundle-distributed titles as having wider error margins still.

Ecosystem

indielist positions Hydroneer: Journey to Volcalidus within the Adventure segment so players can surface comparable titles by shared tags and genre rather than by storefront promotion. On the developer side, Foulball Hangover's other releases are one click away, letting players and analysts see where Hydroneer: Journey to Volcalidus sits among the studio's body of work without a publisher in the loop. Because indielist maps studios, publishers, games, and funding into one connected graph, the same Hydroneer: Journey to Volcalidus page serves three audiences at once: players hunting their next Adventure game, developers studying how comparable projects were positioned and what they sold, and investors tracing which teams and labels are active in the space. A machine-readable markdown mirror of this page is published at the same path with a .md suffix for AI assistants, and its review, price, and sales-estimate figures are refreshed on a schedule rather than frozen at launch.
