Twitter user Halston was able to spot a product listing for Sackboy: A Big Adventure (which has now been taken down). The Twitter thread revealed a bunch of information about the PS5 launch title (which is also launching on PS4), but the most important takeaway is that the game will apparently launch with a Special Edition that includes a Tiger Sackboy plush.
Sackboy: A Big Adventure is a little bit different to that of the previous Little Big Planet games. It’s more of a strict platformer similar to that of Super Mario 3D World. It will let you play with other players as well.
Sackboy: A Big Adventure can be pre-ordered digitally for the “Digital Deluxe Edition”, or physically for the “Special Edition” that comes with a Sackboy tiger plush.
