Can someone help me? I'm on area 100 in the Mushroom Paradise. But i dont know how to get the Event Crusaders....... The Alien Invasion ends soon and i wanna have the new Crusaders really badly. Thx !

Hi Jax, you have to abandon your current objective by either reseting the world or by chosing the first event objective.

If you can't reset but want to stop the objective, go on 'See all objectives' when you move your mouse on the objectives' icon on top of your screen (right to the DPS). This way you can see the first event objective and given you have at least 100 fireworks, you can start the objective to get Billy. Since you have an active objective, you will need to confirm that you want to abandon the current objective and confirm that you really mean it. After that, the objective should start.

One note: If you are on your very first run even before your first reset, you need to reset through Nate by bringing him up to level 150 and using his 'resetting' ability. I don't know, if you are actually able to start the event as your second objective, since it might be too difficult for you, but give it a try and good luck!
