下面是只解开回应所有电话的攻略:
1."Ronald问你要食物，否则他会带房间里全部的人离开"
出现条件: 房间内必须有生还者
需要解救的生还者: 19日出现的生还者(除开始在天台上救的Jeff和Natalie),有一名即可
对应房间: 蓝
不完成后果: Ronald离开并带走房间内的5个人
2.Floyd要求你拿一些酒回到Security Room
出现条件: 无
需要解救的生还者: 无
对应房间: 黄
不完成后果: Floyd自己离开
3.Kindell在Security Room里开始散布谣言
出现条件: 房间内必须有生还者
需要解救的生还者: 19日在天台出现的Jeff和Natalie
对应房间: 绿
不完成后果: Kindell带房间内所有人离开
4.Simone需要一支手枪的电话
出现条件: 主线任务必须做完7-2
需要解救的生还者: 主线任务5-1的ISABELA
对应房间: 黄
不完成后果: Simone自己离开
下面是引用其他玩家对这个成就的分析，我感觉重要的只有两点，一是电话要第一次就接到，并且要听完整，二说的是最好在"Cut From The Same Cloth"杀了Kent（那个照相的人），其实原因就是当Kent遇见你时就会强制说话- -! 这样做的目的就是为了避免Kent和你强制说话时有电话打来，不过你的时间掌握的好，熟悉主、支线任务的发生时间的话可以无视。
