We study a zero-sum partially observed semi-Markov game with average payoff on a countable state space. Under certain ergodicity conditions we show that a saddle point equilibrium exists. We achieve this by solving the corresponding average cost optimality equation using a span contraction method. The average value is shown to be the unique zero of a Lipschitz continuous function. A value iteration scheme is developed to compute the value.
