If you've never played Limbo before, now is your chance to experience something mind-blowing, for free.

Steam is giving away the classic atmospheric side-scroller today and tomorrow TOTALLY FREE. Yup, just sign in for free, download free and – you guessed - get playing on your computer for free.

For those that have not had the pleasure yet, Limbo is an indie game about a boy that enters the black and white world of Limbo to discover his sister's fate. The result is a super chilling but beautiful game filled with horrors and pitfalls. Some parts are ridiculously difficult, most are lots of fun. You won't get bored, that's for sure.

Be warned though. Lots of people get so addicted to Limbo that they end up playing the whole game through in one four hour sitting. So if you had plans to box set binge this weekend, you may want to forget that.

Limbo is available to download right now for free on Windows, Mac and Steam Play. Get in quick before the free deal ends.
