Kill Them All (1970)

Described as a love letter to 1990s action movies, Kill Them All tells of a betrayed murderess on a revenge campaign and a hard-drinking former cop who team up to take down a crime lord. Their nemesis rules from atop a 15-story Miami high-rise, so the duo must go floor by floor cutting through assassins, murderers, Luchadore gang bosses, ex-boyfriends and office workers.
