Sorry there's not much time to chat. We've just spotted a group of infected canines that are currently alight. As you may already know the N4 virus has a very strange reaction when heated to these levels, causing the subject to mutate rapidly. This is a rare oppurtunity to study these extreme mutations in canines.
I've marked the last known location of these animals on you map. Please go there and collect as many blood samples from the burning creatures as you can.
