Basic controls you should remember:

• Ambulance Driver: WASD - move
• Doctor and Assistant: WASD - move, Space - jump, Left Shift + W - run, E - enter the car, R - exit the car
• Navigator: WASD - move, Scrollwheel - up/down, Mouse 0 - set target, Mouse 1 - set quarantine

Main Menu:

You can change your Username in top right corner of your screen. Your XP depends on Team Points gathered in matches.

Game Mechanics:

Every match lasts 38 minutes or until the Public Anger reaches 100%. The match can be won only by good teamwork of all characters.

• Navigator - can set target where the team can find infected. Target can be then  canceled by pressing the "X" button on the UI. He can also set quarantine which can block traffic. This can help the team to fast transport from one place to another but be careful - it also raises the Public Anger! 
• Doctor - can hospitalize infected by going near them. This is his main task - hospitalize as many infected as possible. Doctor can enter and exit car by going to the back side of the ambulance vehicle.
• Assistant - can collect items that are spawned on the place of hospitalized patient. Every collected item rises Team Work points which are after the end of the game added to XPs of all players!
• Driver - can DRIVE! Yes, his main task is to drive and transport his team through the down. The faster he is, the more infected patients are saved! But he has to be careful, hitting the patient with the car will raise the Public Anger!

And that's the whole mechanism of the game. Can you cure them all?
