A few interesting (to me, at least) local Metal Gear Solid connections.

Major Zero's home during Metal Gear Solid 3 is listed as Portsmouth, NH. In the data file written by Natasha, the remaining soldiers from Shadow Moses were captured and incarcerated at Pease Air Force Base (although it's not technically an Air Force Base anymore). I don't think it's unreasonable to assume that Zero, being a former SAS member, operated from Pease.

So that's kind of neat.
