For all of you who might not be current or have forgotten some of the relationships or storyline of the Metal Gear series (NES and PS titles), then worry no more. Available now through the PSN, you can download a Metal Gear Database (77 MB). In the database you will find:
* MG Timeline
* Relationship Tree
* Metal Gear Encyclopedia
The database is simple to use and comes complete with text and photos. It is FREE to download and does not take much space on your hard drive. I highly recommend this add-on. You can use before, during, or after you play the newest game, MGS 4.
