Killer Frequency is a first-person horror puzzle game set in 1987, that puts you in the role of a late-night radio talk show host in small town America whose callers are being stalked by a mysterious killer.
As a late-night radio DJ, you'll receive emergency calls from potential victims of a serial killer stalking the town of Gallows Creek. The core gameplay loop revolves around gathering clues and information around the radio station, then using that knowledge to guide callers to safety through dialogue choices.
The game features a variety of environmental puzzles, such as finding codes and passwords, operating the radio station's equipment, and searching for hidden items. These puzzles require you to pay close attention to your surroundings and piece together the necessary information to progress the story and aid the callers.
Your dialogue choices with the callers have a significant impact on the outcome of each scenario. Depending on the decisions you make, a caller may live, die, or experience a different fate. This branching narrative structure encourages multiple playthroughs as you strive to uncover all the possible endings and save as many characters as possible.
The highly interactive game world allows you to explore the detailed 1980s-inspired radio station, manipulate various objects, and utilize the station's equipment, such as the soundboard, record player, and cassette deck. These interactive elements help to immerse you in the role of the radio DJ and the tense, time-critical situation unfolding around you.
While not relying on traditional "jump scares," the game maintains a consistent sense of tension and urgency through the time-sensitive nature of the callers' situations and the ominous presence of the Whistling Man killer. The pacing strikes a balance between the slower, methodical puzzle-solving and the high-stakes, real-time decisions required to save the characters.
