LittleBigPlanet 3 features gameplay elements very similar to the first two games in the main
LittleBigPlanet series,
LittleBigPlanet and
LittleBigPlanet 2. It is a
puzzle-platform game with elements of a
sandbox game. Like other
LittleBigPlanet games,
LittleBigPlanet 3 places a heavy emphasis on creation. Players create their own levels, characters, and objects, such as power ups, tools, decorations, stickers, or vehicles, hub levels, Pods (effectively the character's 'homebase' that is used to navigate the various levels), and other things. Players may share their creations. The core gameplay revolves around navigating the myriad number of levels with a set character, using power ups, jumping, swimming, swinging, grabbing, interacting with switches and
non-player characters, defeating enemies, completing various main objectives, and finding collectibles, such as Collectabells, stickers, materials, objects, and gadgets.
LittleBigPlanet 3 introduces three brand new characters in addition to
Sackboy, each with their own unique traits and abilities. OddSock is a four-legged, dog-like character who can run faster than Sackboy and can wall-jump. Swoop is a bird-like character who can fly freely around levels and can pick up other light objects. In addition to objects, Swoop can pick up other characters, with the exception of Big Toggle. The larger version, called Big Toggle, is much heavier than Sackboy and can weigh down platforms or pressure plates.
LittleBigPlanet 3 has several power-ups which, when equipped, give players additional abilities. Two such power-ups, the Pumpinator, blows and sucks air to move light objects, and the Blink Ball that when fired at a specific material, can teleport players. In addition to pre-made power-ups, creators are able to make their own using the new Power-up Creator. There are 70 tools in total, in addition to enhanced ones retained from the three previous titles,
LittleBigPlanet,
LittleBigPlanet 2 and
LittleBigPlanet PS Vita. All previous
downloadable content packs from
LittleBigPlanet and
LittleBigPlanet 2 are fully backwards compatible, being transferable to
LittleBigPlanet 3 on both the PlayStation 3 and PlayStation 4 versions. However, story progression logged from
LittleBigPlanet 3s predecessors does not transfer onto the PlayStation 4 version of the game. The PlayStation 4 version of the game is rendered with an improved graphics engine and textures at
1080p resolution, while the PlayStation 3 version renders everything at
720p. Players are limited by the classic Thermometer rules by default, but players can choose to use the new "Dynamic Thermometer" streaming for levels. This makes the game unload objects as the player(s) get away from them and load objects that the player(s) get close to, and only loaded objects affect the Dynamic Thermometer. In addition, players can create Adventures, levels that contain up to 15 other levels that share progress through throughout all the sub-levels. However, on 1 January 2024, a server shutdown occurred, rendering the online community permanently unplayable. ==Plot==
