Brightly-coloured battle royale Fall Guys: Ultimate Knockout has shifted 2m copies on Steam since its launch on 4th August.
The game is also currently available on PlayStation 4, where it is part of this month's PlayStation Plus offering. There's no word yet on how many more people are playing there.
But clearly Fall Guys is off to a brilliant start - and far better than expected, as its servers' early teething issues showed. So many people turned up on day one it had to be taken offline for maintenance. There were further issues at the weekend, as yet more players flooded in. Developer Mediatonic has said it is working on a longer-term fix.
