(Contains No Spoilers)
Metal Gear Solid 4 Database to be released tomorrow on PSN:
For those of you who simply can't get enough of everything MGS, there's surprise for everyone tomorrow on PSN -- an official Metal Gear Solid 4 Database. The Database is a "free, downloadable interactive application that contains the official knowledge base of everything that is Metal Gear, reaching all the way back to the very beginning of the franchise." In other words, all the MGS lore you could ever want in one free official package.
In consideration of those of us who haven't finished MGS4 yet, there is a feature that eliminates any and all MGS4 information for a spoiler-free experience. They also added a camouflage and a new music for the in-game iPod under EXTRAS of the main menu for immediate download. It looks like Konami has a lot of MGS4 DLC up their sleeves, we can't wait!
The Japanese version of the MGS4 Database is up at the Japanese PSN!!
After installation it is not found under Extras in the game menu but rather a separate DLC game. The Japanese download has the option of Japanese, English, French, Dutch, Italian and Spanish. It does indeed asks you if you want to use your save file to unlock any spoilers. Spoilers are locked by default and you need a save of the cleared game to unlock it. There's also a menu for "Briefing" which is for people who have already beat the game, so maybe you get an extra Mission Briefing.
Log on to the Japanese PSN if you want this MGS Encyclopedia one day early!
