Forget about central heating, Sony’s impressive “13 for ’13” promotion is the real winter warmer this week. The excellent initiative – set to launch later today in North America – will see a slew of PlayStation Network titles discounted for the New Year, with PlayStation Plus subscribers securing savings as large as 75 per cent. Highlights include LittleBigPlanet Karting for $10.00, The Unfinished Swan for $3.75, and Jak & Daxter: The Precursor Legacy for just $2.00.

Premium members will also be able to participate in a good old fashioned game of table football this week, when Grip Games’ surprisingly solid Foosball 2012 is added to the Instant Game Collection for free. You’ll be given the option to download both the PlayStation 3 and Vita versions of the title, unlocking a wealth of cross-platform functionality in the process.

Other notable perks include a 20 per cent discount on escapeVektor, which secured a pile of praise in our recent review. You can peruse the full North American PlayStation Plus update – including all of the aforementioned discounts – over on the PlayStation Blog.
