Looking forward to upcoming PS3 exclusive Metal Gear Solid 4: Guns of the Patriots but a bit bemused by Hideo Kojima´s spiralling plot? Us too. Thankfully there's an answer, and it comes in the form of an amazing three part Metal Gear Saga 20th Anniversary video which explains the entire story behind the epic stealth series.

You'll find everything on YouTube here, including details on nuclear conspiracy, insight on the story's characters and a useful timeline of Solid Snake's adventures.

It's amazing to think that the original Metal Gear Solid was released on PlayStation in 1998. Wow. That makes me feel very old.

We heartily recommend every MGS fan checks the video out. If it doesn't get you excited for MGS4 then nothing will.
