Sony is rounding out January in style, by giving away copies of Ninja Gaiden Sigma Plus to North American PlayStation Plus subscribers. The critically acclaimed PlayStation Vita port – which secured a strong 8/10 in our review – will be available for free from 29th January, so make sure you free up some space on your system’s memory stick.

Other additions this week include a 30 per cent discount on both the PS3 and Vita versions of Madden NFL 13, as well as 50 per cent reductions on Gatling Gears, Greed Corp, and Section 8: Prejudice. As always, let us know if you’re happy with the new arrivals in the comments section below. It looks like a solid update to us, but we're sure that there'll be plenty of complaints.
