Maniac Cop 2

After being impaled by a pipe and plunged into a body of water, the now-undead "Maniac Cop" Matthew Cordell acquires a junked police cruiser and restarts his killing spree through New York City.

In order to protect the memory of Commissioner Pike, the corrupt official who originally framed Cordell, the police refuse to inform the public of the nature of recent events.

After handcuffing Susan to the steering wheel of a car and sending her into the busy streets, Cordell kills Theresa by snapping her neck.

After hearing Doyle's announcement, Cordell abandons Turkell, Blum, and Susan and heads deeper into the prison, where he is attacked with a Molotov cocktail by the three inmates who originally mutilated and killed him.

After a few seconds, Cordell's hand unexpectedly bursts through the lid of his casket (in a jump scare) and quickly grabs his badge as the screen cuts to black and the credits roll.

Its called Rig-Ram by Anthony Morson and is from the album Industrial Activity, part of the Focus Music Library – FCD 109 collection.

[9] Anthony Arrigo of Dread Central rated it 4/5 stars and wrote, "Maniac Cop 2 embodies all of the excess that made '80s horror sequels so great".

[10] Mike Pereira of Bloody Disgusting rated it 4/5 stars and wrote, "Maniac Cop 2 delivers a fresh experience while all along staying true to what fans dig about the original".
