The tutorial has been completed and will be implemented next Friday (8-1). There will also be some adjustments and added features but I will go into detail when it is released.

As for the event...
Since this update is mostly about the awaited tutorial and pushing for returning players, there will be an event called "Helping Hand". Players will gain extra money for every kill that they get while near another player and any nearby players will get a small portion as well. So get your friends on and enjoy killing zombies together.
