Fallout, Kingpin, Sacrifice on Steam

Interplay classics Fallout, Fallout 2, Fallout Tactics, Kingpin and Sacrifice have been added to Steam.

You can buy them for £6.29 each or you can squash the Fallout trio into a handy bundle for £15.99.

The Fallout games need no introduction, of course, but one also shouldn't overlook Kingpin - a brutal first-person shooter where you recruit and lead a gang and bash people's heads in with pipes.

Steam also offers 50 per cent off 7/10 PC strategy game Anno 1701 this weekend.

Furthermore, co-op shooter Killing Floor has had a thorough update, the details of which you can read on Steam. There's 10 per cent off the game to celebrate, too.

Chapter two of Telltale's Monkey Island adventure series - The Siege of Spinner Cay - has been released on Steam as well.
