Gametrailers have put together in-depth videos in their ongoing Retrospective series and since the latest (and last?) entry into the video game series, Metal Gear Solid 4 will be released this coming week, they have dedicated the latest to the groundbreaking series. So far, four separate videos have been released and they all do a wonderful job in documenting the series from it’s inception to it’s current state. So take some time and watch these great videos if you feel like catching up to the Metal Gear mythology. But be warned, each entry comes in at around 23 mins. so be sure you have some free time. After you check out the first one embedded here, head on over here to catch the rest. Good stuff.
