I am looking for calm understanding people to play with myself and my 12yr old son. He is a little slow and has learning disabilities. He has a headset but I don't want to let him use it unless I can find a group he can play with that won't bully him. We have tried going online with others before with a headset and once people realize he is a little slower, they gang up on him and attack him instead of the zombies. We live in a small town and it's hard for him to make friends here.
