Following on from earlier news that PC gamers can snap up the brilliant Psyconauts for only a quid, we thought it only right to point out a couple of great deals for Xbox 360 gamers.

This week sees Portal: Still Alive, the standalone XBLA version of the Orange Box classic, for only 800 MS Points, while beginning February 1 you'll be able to purchase the excellent Splosion Man for the bargain price of 400 MS Points.

The one condition is you need to be a XBL Gold member to access the lower prices.
