Ubisoft has launched a winter sale on Xbox LIVE Marketplace, knocking up to 50% off the price of downloadable copies of Assassin's Creed, Splinter Cell: Conviction and Prince of Persia, along with similar discounts on a range of XBLA games and DLC.

Games on Demand versions of Assassin's Creed 1 & 2 have both been reduced to just £8.99 (1080 Microsoft Points) each, with sequels Brotherhood and Revelations available for £11.99 (1,400 MSP) a pop.

A selection of DLC for each game is available for half the usual price, too.

Splinter Cell: Conviction has also seen a similar reduction, knocked down to just £8.99 (1,080 Microsoft Points), alongside Prince of Persia: The Forgotten Sands, again available for £8.99.

Mad Riders, from Dead Island developer Techland has had its price slashed in half, too, to 400 MSP (£3.43), as has Outland, Beyond Good & Evil, Rayman 3 HD, Scott Pilgrim and Babel.
