It appears that Playdead’s Inside will be heading to PS4 in the near future, with the trophy list appearing on Exophase. Usually when a trophy list is uploaded, its PS4 release is imminent. This could be a little bit different, but it more than likely having an exclusive period to Microsoft, but this could be have been 4-6 weeks.
The developers originally stated that the game would release on Xbox One first before finding it’s way to other platforms. The game released on June 29th on Xbox One and Microsoft Windows on July 7th.
Interestingly enough, the game won’t feature a Platinum trophy, which will definitely turn some people off.
