Here you will find attached the original rulebook in two formats (PDF and HTML file). You will also find the rulebook of BANZAI and DESERT war. In the PDF files you will notice that there is some text in purple colour. This is the so called "errata" which is actually corrections or clarifications to the rules which have been added here for your ease. However, it is recomended for new players to read only the black text.
A summary of the basic rules by Jeff Paul is also attached, as well as flow charts created by Richard Irving as player aid while performing various actions.
