DiRT Showdown on the PC is currently up for grabs for free thanks to the Humble Store.
You have to be quick about it though as this deal expires on Saturday, January 14 at 6pm GMT. DiRT Showdown, which released in 2012, is an arcade spin-off of the main DiRT series which provides some light-hearted fun with plentiful jumps and pirotechnics to boot.
The title is probably a bit like Marmite: you'll either love it or hate it, but as it's free you have nothing to lose, so give it a try. We reviewed DiRT Showdown and thought the game provided primal thrills with its collision focused game modes but we felt the physics didn't always appear up to the task.
