If you missed out on picking up your Free Comic Book Day comics at your local comic book store, you can get them from Dark Horse Digital for a limited time!
Both Mass Effect/Killjoys/R.I.P.D. and Star Wars/Captain Midnight/Avatar: The Last Airbender will be available for free download through Dark Horse Digital starting today.
I know both of those were already gone by the time I got to the comic book store (we tried three different ones), so be sure to jump on this opportunity!
