We draw on years of ethnographic investigation into the disaster response practices of fire emergency response, urban search and rescue, and incident command to inform the design of games. Our objective is to support training disaster responders, yet our findings apply to general game design. We identify critical components of disaster response practice, from which we develop game design patterns: EMERGENT OBJECTIVES, DEVELOPING INTELLIGENCE, and COLLABO-RATIVE PLANNING. We expect that, in implementing these patterns, designers can engage players in disaster-responsestyle planning activities. To support the design patterns, we survey exemplar games, through case studies. The paper contributes a set of game design patterns that support designers in building games that engage players in planning activities.
