15 Spiderweb RPGs star in latest Humble Weekly Sale

Spiderweb Software is turning 20 years old, and has teamed up with the Humble Bundle to celebrate in true style - offering a huge stack of games on the mega-cheap.

The core bundle includes Geneforge Saga, Avadon: The Black Fortress, Avernum: The Great Trials Trilogy, and Avernum: First Trilogy, as well as a stack of art and hint books.

If you pay more than aveerage, you'll also score Avernum: Escape from the Pit and Nethergate: Resurrection.

Although you'll note that counting the two trilogies this only adds up to 10 games, it appears that some of them are bundles, because Spiderweb insists the full package includes 15 games with over 450 hours of gameplay.

All games are available DRM-free on Windows and Mac, with some Steam keys and Linux titles on offer.

The Humble Weekly Sale featuring Spiderweb Software will only be available for one week.

To date, the Humble Bundle scheme has raised over $13.7 million for charity; purchasers are able to determine how much they pay for their bundle, and how the proceeds are split between developer, charities and the organisers.
