Run Sackboy! Run! (commonly abbreviated as RSBR) is a free-to-play game released to promote the LittleBigPlanet series. It was released on October 18, 2014 on mobile phones and on January 4, 2015 for the PS VITA. In the game, players run from the Negativitron through The Gardens, Avalonia, and The Canyons. Players may also purchase in-game transactions, such as extra hearts to continue on after dying.
Players can control Sackboy with a simple touch to jump and a swipe to dash to escape the Negativitron. While running, players collect bubbles, which are used to buy costumes, upgrades, and more and hearts, which can be used to let the player respawn where they have died to continue running.
Players also can collect stickers which can unlock an exclusive Run Sackboy! Run! T-shirt for use in almost all LittleBigPlanet games, a gnome Toggle costume, a frog OddSock costume, a pigeon Swoop costume, and various in-game prizes such as hearts and bubbles.
- Once running past The Canyons for one time, The Gardens will reappear at night, Avalonia will be at sunrise, and passing through The Canyons once again will have it appear raining.
- This is the first and only LittleBigPlanet game to not have "LittleBigPlanet" anywhere in the title.
