Switch entry type based on the category I'm trying to use different entry types for certain categories. My category group is called categories, and the slug for Features is features. I have the category group pointed to categories/_entry. As for as I can tell, I've got it set up right. I think their might just be something wrong with my switch code. This is my code in categories/_entry:

{% set categories = entry.categories.first %}
{% switch categories.slug %}
    {% case 'features' %}
        {% include 'categories/_feature.html' %}    
    {% case 'news' %}
        {% include 'categories/_news.html' %}
    {% default %}
        {% include 'categories/_news.html' %}
{% endswitch %}
The above isn't too clear, but what I was trying to do is use different templates for  different category landing pages. It works with the following:

{% switch category.slug %}
    {% case 'features' %}
        {% include 'categories/_features.html' %}   
    {% case 'news' %}
        {% include 'categories/_news.html' %}
    {% default %}
        {% include 'categories/_news.html' %}
{% endswitch %}
