Big Walk, the new co-op adventure game from Untitled Goose Game developer House House, has sold over one million copies within just six days of release, its publisher Panic announced. The rapid milestone underlines strong early demand for the studio's follow-up, a title built around communication and collaborative puzzle-solving rather than conventional combat or competition mechanics.

Panic confirmed the figure via Bluesky, thanking players for their support, fan art and streams, with sales apparently spanning all platforms including PC via Steam, PlayStation and Nintendo Switch 2. The game supports between two and 12 players, who use proximity voice chat or text to solve group puzzles together, and it received a five-star review from Eurogamer, which praised it as "funny, exciting, and deeply rewarding."
