Overview
Steam Marines is a 2014 Indie game developed by Worthless Bums, who self-published it.

The game is available on linux, mac, windows, and launched at $20. As a self-published Indie project, Steam Marines sits among the independent releases indielist tracks where the developer Worthless Bums retained both creative and commercial control, a path many indie studios weigh against signing with a publisher. indielist's white-box method estimates its lifetime sales at roughly 9,000 to 21,000 units, with the full Boxleiter factor breakdown shown on this page rather than a single black-box figure.

Methodology & limitations
Sales estimates use an additive Boxleiter-derived heuristic against public Steam review
counts. They are not authoritative sales data, and the fixed display range
is not a statistically validated confidence interval. Actual results may fall outside it,
especially for deeply discounted or bundle-heavy titles. Algorithm version
v1.0. Read the exact method and validation status.
indielist estimates lifetime unit sales for Steam Marines at roughly 9,000 to 21,000 copies, with a median around 15,000, derived from its 219 Steam reviews using a multi-factor Boxleiter method (version v1.0). That median maps to approximately $175K 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
Players looking for games like Steam Marines can compare it on indielist against semantically similar Indie titles such as Stardew Valley, Euro Truck Simulator 2, Project Zomboid, Undertale, ranked by shared tags and genre rather than by ad spend. On the developer side, Worthless Bums's other releases are one click away, letting players and analysts see where Steam Marines 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 Steam Marines page serves three audiences at once: players hunting their next Indie 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.
