In honor of Earth Day 2012, Dark Horse Comics is offering a FREE digital copy of Brian Wood and Kristian Donaldson‘s The Massive one-shot.

Collecting parts 1-3 from Dark Horse Presents, The Massive tells a story of three people whose lives were changed as a result of the environment. These three made it their goal to each become environmentalists on a mission to save the planet after the world has already ended. And Dark Horse is giving you the opportunity to read the comic that acts as a prelude to the upcoming series in a paperless, eco-friendly way for absolutely no cost.

Starting from this morning, this free copy will only be available on Earth Day when the one-shot goes back to its regular price of $.99 when the clock strikes 11:59pm, so make sure that you are able to get your virtual hands on this comic while you still can. I’ve already read it, and while The Massive certainly doesn’t feel like a complete story (it’s not, it’s the beginning of a new series), both the writing and art are incredibly strong and the story content was enough to get me on board with the entire series.

So make sure to go here and pick up this great comic for free while you still can.
