Emergency 4 boasts a rich mix of gripping real-time strategy game and true-to-life simulation. The player becomes head of operations in a fictional rescue and catastrophe management organisation, in command of a number of vehicles and staff from the fire department, medical rescue, police and technical services. For the first time in the history of the Emergency series, all campaign missions are embedded into one continuous game set in a real town with a sheer infinite number of side-operations and tasks, so linking the various missions together. The player has to manage money as well as setting the right pre-requisites for upcoming missions. The player has to react to a variety of events, developing dynamically 24/7, set against a background of continuous day/night changes and constantly varying weather conditions.
