Serving as a paramedic, your goal in the game is to deliver the patients in need to the hospital in the swiftest manner. The game starts with an emergency call stating the patient's location. Then click the OK button on the screen or press spacebar on your keyboard to start the mission. Use the four arrow keys on your keyboard to control the ambulance and get to the destination as quickly as you can. Follw the directions indicated by the compass on the left, travel to the designated locations marked by green circles to pick up the patients and then send them to the hospital. The ETA at the top left corner shows the estimated time of arrival, and you should aim to complete a mission within the ETA so as to receive more experience points and to be promoted. Note that even though you are rushing, you need to be careful on the road as the ambulance may hit and crash if you do not play by the rules. The level of destruction is indicated by the green clamp at the bottom right corner. Whenever the ambulance is crashed, a part of the green color will turn to red. The clamp will completely turn red when the ambularnce is totally damaged, and you will lose the game. If you do not crash the ambulance, you may continue to play until the progress bar at the top is filled. Try to save as many lives as possible until your shift ends! Use mouse!
