The game is available on linux, mac, windows, and launched at $11.

Within indielist's catalog of indie games mapped to their studios, publishers, and funding, The Binding of Isaac: Afterbirth can be compared against similar Action titles and benchmarked on review counts and estimated sales.

indielist estimates lifetime unit sales for The Binding of Isaac: Afterbirth at roughly 436,000 to 1.0 million copies, with a median around 726,000, derived from its 8,068 Steam reviews using a multi-factor Boxleiter model (version v1.0). That median maps to approximately $4.6M 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 The Binding of Isaac: Afterbirth within the Action segment so players can surface comparable titles by shared tags and genre rather than by storefront promotion. On the developer side, Nicalis, Inc.'s other releases are one click away, letting players and analysts see where The Binding of Isaac: Afterbirth 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 The Binding of Isaac: Afterbirth 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.
