From their website:
This classic 1984 issue includes the fiction story The First Round. In this story, famed Orion Pirate captain Deth O’Kay is kidnapped by the Masters and forced to fight starship duels in an arena. Also included are:
Four modified SSDs for the ships of the Masters
The first draft of the D15 ground combat rules
And a full-page portrait of a Gorn captain.
A typesetter error in the original production left out two sections of text which were published later, and these are included here.
