Graveyard of the Living Dead

Some gothpunks encounter the undead scientists in a graveyard, and the gory mayhem brings more zombies up from the graves. While the zombies proliferate and munch on some of the youths, the rest find ways to chop up the zombies with various weapons, and there's some amusement as they look for their car keys inside their dead friend and zombie stomachs, creating more gory mayhem than the undead.
