Go through a series of obstacles, gathering a crowd along the way. At the end of your path, a boss is waiting for you, which you need to defeat. To do this, you need to collect a certain number of people.
If there are fewer of them, then you may not be able to resist the one who is waiting for you at the end. If it is equal to or greater than the number, then you can go to the next level. In Join and Clash 2 you have to go through many levels, which constantly becomes more difficult.
Obstacles appear that prevent you from collecting everyone. Even if you don’t manage to do everything the first time, then don’t be discouraged and just keep moving forward and collecting people. It is quite an interesting and exciting runner without difficult controls, so it is possible for you to have a great pastime.
