So they would need the cooperation of more people to deal with level 2 zombies easily.
If they encountered two level 2 zombies, two people would try to deal with one while they waited for the three people to finish dealing with the other zombie.
After the three people with the level 2 zombie, they would help the other two in dealing with the other zombie.
If there were more zombies in their surroundings, they would always try to lure and deal with the faster level 2 zombies first before dealing with the level 1 zombies.
They had been cooperating a lot before, so it didn't take too much time before they got used to cooperating with each other and dealing with at least level 2 zombies.
When they were traveling with Treyton and the others and dealing with the zombies they encountered, the kids wouldn't all be together, but they would be cooperating with the other people in the team.
For example, Austin and Owen had mostly been cooperating with Max and the others.
