The folks at PSP Vault have combined the GPS accessory (now available in Japan) with the recently releasedMetal Gear Solid: Portable Ops. As explained earlier, you'll be able to recruit new soldiers through this weird and wacky feature that combines virtual espionage and real-world location hunting. Check after the cut to see more.
The little circles seen on the GPS are soldiers you can recruit. According to the Vault's estimations, the large circle that's represented on the screen spans a distance of half a mile: perfect for a lengthy hike on foot. When you get within 100 feet, it seems like you'll get a new soldier to join you.
Whether or not you think this feature is lame or cool, there's no denying that this is truly an original and imaginative addition to the MGS universe.
