So, as GS promised, those who preordered or reserved MGS4 would get a code that would let you access the online play beta being released the 17th. It also came with a short DVD explaining all of the Snake's relationship to each other and foxhound.
The DVD is short, only about 25 minutes to the actual movie. The movie is just gameplay with talking over it and the occasional spreadsheet showing peoples relations to each other.
The chapters are:
CHAPTER 001: Prologue (Prologue)
CHAPTER 002: Metal Gear 20th Anniversary
CHAPTER 003: Big Boss - The Origin Of Snake
CHAPTER 004: Liquid - The Second Snake
CHAPTER 005: Solidus - The Third Snake
CHAPTER 006: Solid - The First Snake
Also, there are all the official trailers on this DVD. It's pretty cool, there are some that i haven't seen on YouTube yet, but that could just be poor search results.
I'd go throw down $5 for this if you haven't. Even if it isnt much, it looks pretty next to the rest of my Metal Gear Solid collection.
