22 Valve titles for £70

With the highly-anticipated Left 4 Dead just a week away, Valve is giving gamers the chance to buy its entire back catalogue for under $100 (£70).

The Complete Pack is available to download via Steam, and features 22 titles including the entire Half Life series, Portal, Team Fortress and Counter-Strike, which has an individual price of $230.

Left 4 Dead is also included in the pack, and Valve revealed last month that in North America the game’s pre-orders are 60 per cent ahead of The Orange Box.
