Brian Wood’s eco-disaster comic The Massive is nearing its third year, and to celebrate Earth Day, publisher Dark Horse is offering up the first four issues for free (along with a pretty cheap bundle for the 22 issues released so far).

The Massive tells the story of a crew of environmentalists attempting to survive an ecological catastrophe while searching for their titular sister ship in a world gone nuts. It’s less action disaster story and more slow-burn drama as we hang out with Wood’s “direct action environmentalist” protagonists.

The Massive‘s free starter bundle is available in the Dark Horse Digital store, along with the $10, 22 comics bundle collecting every issue of the series so far.
