The Humble Bundle store, popular for its low-priced and charity-based game bundles, is currently running a giveaway event for DiRT Rally (Windows, Mac & Linux), to be claimed on HB before September 01 at 10am PT (to redeem on Steam before Sept. 05). Here is everything you need to know.

DiRT Rally

DiRT Rally (2014) is a positively reviewed Dirt Rally racing video game developed and published by Codemasters for Microsoft Windows, normally sold $40. DiRT Rally is the most authentic and thrilling rally game ever made, road-tested over 80 million miles by the DiRT community. It perfectly captures that white knuckle feeling of racing on the edge as you hurtle along dangerous roads, knowing that one crash could irreparably harm your stage time.

How to unlock DiRT Rally

All you need to do is to go to the Humble Bundle’s page to claim the key by pressing the big green “Get the Game” button. Then follow the instructions (such as creating an HB account if you don’t have one, and linking a Steam account), to get the key link sent to your email address. Once you have your own game key, head over to Steam to redeem it.

Note that claiming the game also implies that you subscribe to HB’s newsletter (box ticked by default). This promotion is available until September 1st at 10 a.m. PT.
