At Mana Press we have been playing a fair few Gladiator games over the years. Last year, Adam provided a few more addendums to our Tribal rules for Gladiatorial combat - which we used for our Little Wars Adelaide Tribal game. It was good fun, and Adam has formalised some of these changes into a supplement for Tribal.
We would like to offer this supplement for free - just purchase it (at $0) through our shop on the Mana Press page.
Please enjoy and have fun playing!
