Valve is offering players one of the best PC gaming bargain bucket deals ever known to man – the studio's entire back catalogue of 22 superb games, including its newest game Left 4 Dead, for a mere $99 dollars.

Valve: The Complete Pack includes three CounterStrike games, ten Half-Life games, Portal, Team Fortress 2 and the Day of Defeat series, among other gaming gems to keep you more than happy through the holiday season.

If you wanted to buy the lot, then Valve would previously have charged you $235.

If you happen to have missed out on any of the must-play episodes of Half Life 2 over the last year or two, then the pack is already worth investing in.
