LittleBigPlanet Karting's Cross-Compatibility Pack DLC is available today for free and allows players to use DLC costumes from LittleBigPlanet 2 and LittleBigPlanet PS Vita in the kart racer, according to a post on the official PlayStation Blog.
All costumes purchased the future will also be available across the range of LittleBigPlanet titles. Only a few costumes — notably those from Assassin's Creed — are incompatible with the update, according to an FAQ on the LittleBigPlanet website. Other costumes may take a while to incorporate, as the developers "literally had to rebuild all of these costumes from scratch again for each game." You can find installation instructions for syncing up the updates and systems on the FAQ.
A DLC pack called Emergency Services for LittleBigPlanet 2, LittleBigPlanet PS Vita and LittleBigPlanet Karting is also out today, allowing players to dress their sackpeople as a Policeman, Fire Fighter, Medic or member of Sea Rescue. It also introduces emergency-themed vehicles to LittleBigPlanet Karting. For more on karting LittleBigPlanet style, be sure to check out our review.
