Humble Bundle Inc. is offering another "pay whatever you want" bundle of games. This latest package features the work of Introversion Software, a small indie studio from England.

By purchasing the bundle, you'll get Uplink, Darwinia, DEFCON and Multiwinia. All of these games work on PC, Mac, or Linux systems. Introversion has also thrown in two Windows-only tech demos. The first demo shows a complete city being constructed with procedural generation, while the second features destructible voxel buildings.

So far Humble Bundle Inc. has raised over $208,000 through the sale of this package. The highest amount paid was $1,024 and the average is about $3.65. If you pay more than the average, you'll get two more games: Crayon Physics Deluxe and Aquaria.

As usual, you can not only choose how much to spend on the bundle but also where the money goes. You can choose how to split your cash between the developers, the charity Child's Play, digital rights advocacy group Electronic Frontier Foundation and and Humble Bundle Inc. You can literally choose where every cent goes.

This collection of games will be available for the next two weeks.
