Snatch all the sweet gear and dual wield assault rifles, wear a bulletproof vest and then seek the lord of this shithole town.
Get in a new police car and use the GPS thingy to find "City hall".
You change cars, finding a spare cruiser in the lot. After packing the supplies you want into it, you use the GPS to find City Hall easily enough, and you start driving out to it. It's actually pretty close.
Hm. Let me try. When City Hall is found, ram through the doors with the car and fill everyone in the lobby with lead rhythm.
+1
City hall is a three story, sort of ugly modern thing with an arched double-door entrance at odds with the brutal-brushed concrete finish architecture the building displays. There's a sign that declares this building a combination of a courthouse and city hall. Normally it would be closed, as it's the middle of the night, but the crisis across town you started has necessitated the arrival of some sort of crisis management team. There's a pair of tense looking security guards at the front door, and people rushing in and out of the building.
You rev the engine.
Using a little essence (-10) to give the police cruiser an extra oomph, you slam on the gas and hurtle forward. The security guards panic and dive to the sides as the car soars up the stairs and blows the front doors off their hinges. The doors fall to the floor and crack the marble tile, and the police cruiser glides forward and smashes into a statue of an angel holding a pair of scales. The statue topples over but the cruiser also is halted, smoke pouring out of the hood. You climb out of the car, as several people rush towards you. There's a crowd of functionaries and clerks, all staring. They back up when they notice you're holding an assault rifle in each hand. Then you start spraying down the room.
The first group of unfortunates in your way get mowed down before they even realize what's going on - again, the people who were going to try and help you, which sort of seems to be your signature style. After that, everyone starts screaming and running, and you empty the clips of both rifles pretty rapidly. A security guard from the entrance takes cover around the door frame and starts shooting at you, but he's of no real importance. You pop the trunk of the cruiser open and take out the shotgun, and empty that into the guard behind the doorframe, the counters that some of the crowd are taking cover behind, and also the fire extinguisher for looking at you the wrong way.
Once you are out of ammunition, the only sounds are people sobbing or groaning and the police cruiser's engine whining. You stride over to one of the injured, a young man squirming and clutching at the bullet hole in his stomach, and pick him up by the throat and hold him up.
"Where's the mayor?" you demand. "Tell me, or I'll disembowel you."
"Uch, hyerck...Theeh, theh mayorsh dead. You sshot him." he sputters, pointing to one of the corpses.
"Oh. Whoops." you drop him and look around the room. "Okay, who's in charge if the mayor is dead."
Nobody says anything, so you reach down, grab the man again, hold him up for everyone to see and crush his skull. "Okay, gonna ask again. Anybody?"
Someone very timidly steps out from behind the counters, points at another corpse, crouches behind the counter as you sigh wearily. "Okay, great, WHO IS IN CHARGE THAT IS STILL ALIVE!?"
From the back, someone wails. "We don't know!"
What now? >_
