From the publisher:
Tide of Iron puts players in the thick of WWII. The Tide of Iron Map Upgrade pack lets players update their original map boards with brand new artwork and enhanced colors. Players can also use these with their existing Tide of Iron boards to create epic level battles.
Also included is the cardboard from the base game with upgraded obstacles such as tank traps, bunkers, and hills, giving players much more flexibility when creating custom scenarios and recreating famous battles.
