BOOM! Studios has added its name to the list of publishers embracing Humble Bundle with a promotion that allows readers to name their own price for digital editions of comics ranging from RoboCop to Lumberjanes to Mouse Guard.

By now you likely know how Humble Bundle operates, with customers getting DRM-free downloads for as little as a penny, with a portion of the proceeds going to a charity (in this case, the Comic Book Legal Defense Fund).

As usual, the offer is broken into tiers, with any price getting: Imagine Agents #1-4, by Brian Joines and Bachan; Evil Empire #1-3, by Max Bemis, Ransom Getty and Andrea Mutti; Curse #1-4, by Tim Daniel, Michael Moreci, Colin Lorimer and Riley Rossmo; Day Men #1-3, by Matt Gagnon, Michael Alan Nelson and Brian Stelfreeze; Dead Letters #1-4, by Christopher Sebela and Chris Visions; Hit #1-4, by Bryce Carlson and Vanesa R. Del Rey; Sons of Anarchy #1-11, by Christopher Golden, Ed Brisson and Damian Couceiro; RoboCop #1-2, by Joshua Williamson and Carlos Magno; and RoboCop: Last Stand, Part 1, by Frank Miller, Steven Grant and Korkut Öztekin.

Those who pay more than the average amount offered (right now, that's $9.34) also get Six-Gun Gorilla #1-6, by Simon Spurrier and Jeff Stokely, Translucid #1-3, by Claudio Sanchez, Chondra Echert and Daniel Bayliss, The Woods #1-3, by James Tynion IV and Michael Dialynas, Hacktivist #1-4, by Alyssa Milano, Collin Kelly, Jackson Lanzing, Marcus To and Ian Herring, Mouse Guard: The Black Axe, by David Petersen, Planet of the Apes, Vols. 1-4, by Daryl Gregory and Carlos Magno, and more titles to be announced later.

And $15 or more unlocks Bravest Warriors, Vol. 4, by Joey Comeau and Mike Holmes, Bee and PuppyCat #1-2, by Natasha Allegri and Garrett Jackson, Lumberjanes #1-4, by Grace Ellis, Noelle Stevenson and Brooke Allen, and The Midas Flesh #1-8, by Ryan North, Braden Lamb and Shelli Paroline.

The promotion ends Aug. 20 at 11 a.m. PT.
