Do you like free games? Of course you do. And for the next slightly-less-than-a-couple of days, you can get the Dirt 3 Complete Edition completely free from the Humble Store.

We didn't rate Codemaster's 2011 rally racing sim Dirt 3 quite high enough to warrant a blurb in the Complete Edition trailer, but we liked it an awful lot. It features "iconic cars representing 50 years of off-road motorsport across three continents," as well as the freestyle Gymkhana mode, Rallycross, and others, with "genre-leading" damage modeling, and split-screen and online competitive multiplayer. (The pickings may be a bit slim for online play, though: It's been five years, after all.)

The Complete Edition bundles the original game with seven separate DLC releases:

The Monte Carlo Rally Pack – eight breathtaking Rally stages featuring dramatic climbs, descents and hairpins of snowy mountain roads. Race through the Alps and conquer the legendary Col de Turini pass.

The package normally goes for $30/£23, but is flat-out free, for keeps, from the Humble Store until 1 pm ET on Saturday. Just go to the site, click the "get it free" button, link your Steam account (if you haven't already), and then check out. You'll be given a Steam key, accessible via your Humble download page; redeem it on Steam, and you're off to the races.

One catch: For reasons I don't understand, the Steam key redemption deadline is 10 am PT on November 19, so be sure to slam it into your account as soon as you get it.
