Since its release in January, LittleBigPlanet 2's community has created more than four million levels for the PS3 platformer. The number is exactly 4,141,742, in fact.
Sony announced the milestone along with plans for Killzone 3-themed Sackboy costumes [pictured] , arriving next month. A set of Tron: Evolution costumes arrives April 26 for $US2.99. The Killzone 3 costume wasn't priced or given date more specific than May.
