Microsoft has significantly lowered the price of many popular DLC bundles on Xbox Live as part of a special promotion called Extended Play Download Days.

The packages, listed in full below, are being reduced by varying degrees, offering up to 60 per cent off some of the most popular selections around. Well, Microsoft says they're popular.

Some are clearly going to be of more interest than others. Nobody's blood pressure is going to spike over a GBP 0.51 reduction for an extra Beautiful Katamari level, but The Shivering Isles with a third knocked off will probably send rat-punchers into spasms of ecstasy.

The price changes are active now, and they'll be in place until the end of October.
