Including complete storylines, character profiles, relationship diagrams, and much more! The MGS4 database is a great way to catch up for someone new to Metal Gear, as well as a useful resource for any veteran of the series, with complete official details on every aspect of the intricate Metal gear lore.The MGS4 Database also contains a special feature – if you want to make use of the database, but have not yet fully played through MGS4 yet and are worried about spoilers – all MGS4 spoilers are “blacked out” until you’ve beaten MGS4. Give it a try!But that’s not all, within MGS4, check out the EXTRAS option of the main menu (if you haven’t already). There’s already new, free downloadable content available for the game - with new camouflage and a new music track for the in game iPod. There will be more forthcoming, so be sure to check this often!
