Scientific Problem: Executioner Zombies

Listen, we've got a disaster in the making here! Some particularly dangerous Executioner Zombies have escaped from the Necro-Incubator, and they're now loose on the western bank, as if it's their own amusement park!
These folks aren't your run of the mill zombies − they're real masters of fear and violence. We need to eliminate this threat and learn what kind of technology was used to create them.
Be prepared for unexpected twists: perhaps they will even try to "talk" to you about their plans for conquering the world!

Has the experiment been conducted successfully?

So, have you dealt with these Executioner Zombies? Excellent! We will now be able to study their methods and learn exactly how they've become so "proficient" at their trade. The data we receive brings us closer to the completion of the Wireframe project.
