Humble Bundle offers downloads of the Humble bitComposer 4-Game Bundle for Windows for whatever you want to pay. If you opt to pay the bare minimum of $1, you'll get Air Conflicts: Pacific Carriers, Galaxy on Fire 2: Full HD, Thunder Wolves, and Jagged Alliance: Classics. That's $62 under the lowest price we could find for downloads of these games elsewhere. If you pay $6 or more, you'll also get Jagged Alliance: Crossfire and Expeditions: Conquistador, a total price low by $106. Your contribution can be donated to charity (Child's Play or the American Red Cross), bitComposer Games, Humble tip, or all. Deal ends November 21 at 2 pm ET.

Note: A Steam account is required for activation and select games are also available for Mac and Linux.
