Australian indie studio House House announced that its co‑op‑only open‑world puzzler Big Walk has sold one million copies within just seven days of launch. The rapid uptake is striking given that the game is currently offered as a monthly free title on PlayStation Plus, meaning many players receive it without purchasing a copy, and it also ships on Nintendo Switch.
The milestone eclipses the studio's earlier breakout, Untitled Goose Game, which needed three months to hit the same figure. While Big Walk's sales trail behind 2026's runaway indie hits—Meccha Chameleon (1 M in four days) and Mewgenics (1 M in eight days)—they still surpass titles like Mina the Hollower, which moved half a million units in eleven days. Critics have praised Big Walk for its relaxed, disaster‑filled co‑op play, noting the absence of matchmaking, scares, or death screens, and its serene aesthetic.
With a 25 % launch discount still active on Steam, the game’s success underscores a growing appetite for peaceful, multiplayer experiences. Observers suggest the strong performance could encourage more developers to explore low‑stress co‑op designs as the genre gains momentum.
