Playdead has released their black and white platformer, LIMBO, on the PSN. It's available in North America, Europe and Asia ($14.99 North American price). It will be released in Japan on August 4. It's also due out on Steam on August 2.
Limbo is a visual puzzler featuring hand drawn backgrounds, traps, desolate cities and one little guy who has to make his way through it all. The game is available for demo now on the PSN for those who want to try it first before playing.
And if you're still feeling a little twitchy about the cash in your hand, Sony will give a 20% discount for two weeks for the game for PlayStation Plus subscribers as a present.
