MGS4 database on PS3 Store today

Sony will be popping a special Metal Gear Solid 4 database application on the US PlayStation Store today.

It's free to use and has an official brain that knows everything about Metal Gear, according to the Sony US blog. That means complete storylines, character profiles, relationship diagrams and more.

So if you want to play MGS4 but were a bit worried you knew nothing about the series, this will be a good place to start.

The program also sounds as if it knows when you finish Metal Gear Solid 4 (it is a brain) as until you do, spoilers will be blacked-out to avoid ruining your summer and maybe your life.

And yes it gets more exciting with an extras option in the main menu that gives you access to free downloadable content. So far there is a new camouflage for Snake plus some music to play on your in-game iPod. More to come, apparently.

There's no word on whether Europe will also get access to the database, but we're literally checking right now. Besides, you could always be cheeky and set yourself up with a US PSN account anyway.

Metal Gear Solid 4: Guns of the Patriots came out last Thursday and became the biggest-selling PS3-exclusive over its opening weekend so far.
