Shot and Shell is an extension of the Yaquinto game Ironclads and includes a conversion chart. Scale is 100 yards per hex, 3 minutes per turn, with 1 ship or regiment (of infantry, or equivalent in cavalry or artillery) per unit-counter. 27 scenarios and 6 maps.
Shot and Shell can be treated as a stand-alone game. It comes with everything needed to play.
The land-warfare dimension is greatly expanded in Shot and Shell (over that of the Ironclads Expansion Kit). Scenarios can be naval only or land-sea combined--or even land-only, if one wanted to design such a scenario. There are also rules for firing several same-caliber guns at once, reducing the amount of die rolling.
