Due to what we’re suspecting must be an error, Knack 2 is currently free in numerous regions.
Update: It seems to have been fixed on the Australian store, meaning that this may have shifted from a story about a thing that is happening to a thing that happened. There’s a possibility that it won’t have been fixed in your region yet, though.
Original story: This presumably won’t last, but Knack 2 is free in several regions right now, including Australia, New Zealand, Spain, and Russia (and presumably others – it’s difficult to get the full scope right now).
Here’s the game’s store page – see if it’s free in your region.
When I asked on Twitter if anyone had managed to get the game downloading onto their PS4, I had confirmation that people in Australia and Spain are currently downloading the game after purchasing it for free.
We’ll update this post if the situation changes (and there’s a past precedent for people not getting to keep the game afterwards in situations like this, like the Xbox Fallout 4 debacle), but for now, go forth and download.
