Is simple when hulkers spawn do not kill the infected you need to tell everyone around you not to kill the infected concentrate on hulkers you will see the round bar will slow down an give you plenty of time to kill 1 maybe 2 hulkers. But it will only work if everyone stops killing the infected. Also do not usually infectors or bmg's which that means no bugs will kill infected or bmg to attach to infected pretty simple.
I've had better luck at night getting the Hulkers to die. During the day, most people kill any and everything. During the evening (PST) I see more people focused on killing the Hulkers.
