Series synopsis: Halo: Helljumper is an unofficial web series (made by fans) based on Microsoft's acclaimed video game franchise, Halo. Adapted from the short story, "Dirt," By Tobias S. Buckell, it tells the story of a few human ODSTs as they fight through 27 years of brutal war with the Covenant. They evolve from a rag tag group of recruits in the UNSC to being cold battle hardened veterans that are shadows of their former selves.
This is truly amazing. Though iffy at parts and the performances aren't the best, the Halo fanboy in me completely overlooks all of these small flaws. It's what I'd imagine a film to be like. God bless these fans for making this series, you can check out their IndieGoGo page and donate so they can continue making the series past episode 2.
