The training can be done alone or with multiple players up to 16. Each participating player can choose to control squads from one or more agencies; take control of one or more incident command sections; or be an observer. After a tutorial on how to manage an emergency-response scenario through the provided software and computer tools, crisis scenarios are addressed from the perspective of the Incident Commander System, either alone or as a team. The scenarios portrayed are a school hostage situation, a courthouse bomb threat, a chemical spill, and a severe storm. Each scenario offers different challenges to the players. In some situations, law enforcement is the emphasis. In others, fire-fighting is the greatest challenge. Others may confront players with downed power lines, water-main breaks, noxious chemicals, and the media. Recognizing which threats are greatest and dealing with them by effective use of the Incident Command System and effective deployment of responders are the keys to success and a high score in the training. Crisis scenarios are managed through detailed maps displayed on the computer screen. The maps include icons that can be selected and moved to perform selected tasks at various locations on the map.
