Trivia / The Hong Kong Massacre

• Dueling Games: The Hong Kong Massacre takes obvious inspirations from Hotline Miami. A couple of months later, it was up against two more games that take the same inspiration - God's Trigger and Katana ZERO. However, the former is geared for co-op and has two distinct characters with a range of supernatural abilities, whereas the latter was done in side-view (rather than overhead) perspective and with a much greater storytelling focus.
• What Could Have Been: The prototype trailer shows a number of features that didn't show up in the final game, among them being able to shoot multiple targets while dual-wielding and using night vision goggles. The story's Framing Device also had gameplay effects, with levels changing depending on how the player responded to questions during interrogation.
