House of Velez is a horror game based around stealth/puzzle elements. It emphasizes sneaking, running and hiding mechanics to surpass obstacles rather than combat. The game features a "Focus Mode" that allows you to see your pursuers' field of vision and hearing radius, while also monitoring your own noise levels. Another feature is "Heart Rate Suppression" that restricts movement, but allows you to become "invisible" when used effectively. House of Velez draws inspiration from titles like Haunting Ground and even film such as the 1980's Hellraiser.
