The Sons of Mars Essentials deck consists of 90 cards that include all the skills and weapons along with one sheet of blank cards for gladiator recording.
A black & white version for ink saving along with the ubiquitous Sons of Mars parchment style PDFs are included. The sheets include a standard card back for those that want to print on both sides of the cards. The sheets are formatted for letter sized and A4 paper.
These cards in spite of their name are not required to play Sons of Mars but after the free quick reference sheet are the first essential accessory.
