(STORY EXTRACT)

What I got instead, however, was heavy automatic cannon fire. My head jerked around for a moment, trying to find the source of it, another spray of the massive bullets whizzing past me instead encouraging me to dive to the ground and try to get out of the line of fire. Okay, autocannon, kind of a familiar sound, too… twenty millimeter, just like Featherweight's. We haven't sold anything in twenty millimeter flavor to Hopeville, so it must be somepony carrying it… but who would be carrying a friggin' twenty mil autocannon?! And, more importantly, why aren't they on our side!?
