Where the Official Specs Live
The definitive minimum and recommended specs for the PC/Mac version are published on the Steam store page (app 1478500). Always check there before buying — that's the source of truth for CPU, RAM, GPU and disk space.
PC (Steam) & Mac
Big Walk on Steam supports Windows and macOS. It's a low-intensity co-op title, so modern laptops and desktops run it comfortably; older Macs vary by model, so confirm against the store's listed macOS version. One purchase covers both OSes on Steam.
PS5 & Switch 2
On PS5 and Nintendo Switch 2 there are no "system requirements" to meet — the hardware is fixed and the game is built for it. You just need the latest system software and enough storage to download. See the PS5 and Switch 2 pages.
Can My PC Run It?
If your machine handles other cartoonish co-op or indie 3D games, Big Walk will almost certainly run. For the exact cutoff, compare your spec against the Steam store listing. Crossplay means you can also play with friends who are on console.
If It Won't Start
On Steam, use verify integrity of game files; update GPU drivers; ensure you meet the store's listed specs. More launch fixes are in troubleshooting.
