The Last Submarine is a campaign by Jeff Billings and John Caskey, and is the first in the Last Submarine Trilogy. The campaign is centred around the recapture of the last operational submarine, the SSN-705 City of Corpus Christi, a Los Angeles class fast attack nuclear submarine. The SSN-705 vanished in the latter part of the war, and the players are tasked with finding and recapturing it. Image:Stub.png. You can help My English Wiki by expanding it.
