Core Keeper

Overview

Core Keeper is a 2024 Action game developed by Pugstorm and published by Fireshine Games. On Steam it has gathered 48,722 player reviews, 93% of them positive, which counts as a very positive reception among indie titles in the Action category. The game is available on linux, windows, and launched at $20. The pairing of developer Pugstorm with publisher Fireshine Games is one of the studio-publisher relationships indielist tracks, letting players find comparable games and letting developers and investors study how Action projects reach the market. indielist's white-box model estimates its lifetime sales at roughly 1.8 million to 4.1 million 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, Core Keeper can be compared against similar Action titles and benchmarked on review counts and estimated sales.

indielist estimates lifetime unit sales for Core Keeper at roughly 1.8 million to 4.1 million copies, with a median around 2.9 million, derived from its 48,722 Steam reviews using a multi-factor Boxleiter model (version v1.0). That median maps to approximately $33.4M 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 Core Keeper within the Action segment so players can surface comparable titles by shared tags and genre rather than by storefront promotion. On the developer side, Pugstorm's other releases and Fireshine Games's wider catalog are one click away, letting developers benchmark where Core Keeper sits among a studio's body of work and how its publisher's portfolio performs. Because indielist maps studios, publishers, games, and funding into one connected graph, the same Core Keeper page serves three audiences at once: players hunting their next Action 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.
