It's not the lowest price we've seen for Sunset Overdrive, but this offer for a download code from CDKeys is currently the cheapest deal around. Make sure to use the 5% off Facebook voucher code by using the widget at the top of the store page. This anarchic and angry game brings "infectious energy, breathtaking traversal, silly weapons" and a "violently colourful playground" to Xbox One, and do so in style. You'll get the Day One edition to boot with extra DLC.
Also, see what I did with the title? Driven under? Oh come on, I thought it was funny.
BuzzDuraband reminds us that the Sunset Overdrive Nordic physical copy is still £24.95 at Coolshop. The game is in English, but resale value is questionable due to the Nordic packaging. Still well worth considering, though, especially if you tend to lend or swap your games out.
