Marathon: Durandal video takes us back

We like us some Marathon. That is no secret. For many people, however, Marathon: Durandal on Xbox Live Arcade will be their first experience with Bungie's seminal shooter. If you find yourself in such a situation, you may find the video above to be an edifying experience. The game packs some serious action as well as many features that were very new during Marathon's heyday, including reloading weapons, alternate fire, and dual-wielding. Oh yeah, and the ability to look up and down? Well that was just crazy (and something you wouldn't find in DOOM, for example). The fact that it also serves as a basis for many of the weapons, story elements, ideas, and concepts of Halo is just gravy. Watch and enjoy.

If you're really inclined to delve into Halo's history, you can grab the entire Marathon trilogy for free.
