From the Avalanche Press website:
Workhorses of the sea, the lowly transport made operations possible: hauling fuel and supplies for fleets and armies, bringing invasion forces to their beachheads, and carrying the trade that kept economies running. In Second World War at Sea games they’re fittingly anonymous, blue-gray pieces used by all nationalities.
That changes with Transports: 280 “long” pieces, in American, Japanese, British, German, Italian, Dutch, Soviet and Norwegian colors – both large and small models, each on a full-sized piece with the top-down drawings that brought you to Second World War at Sea in the first place. This is a great add-on for any Second World War at Sea fan.
Transports is sold exclusively via .pdf download. The playing pieces are not die-cut-and-mounted, nor are the scenario book or the ship data printed. Instead it comes as a series of .pdf files that will need to be assembled into the game's components.
