EPS Engineers Full-Venue Pipe Grid for Universal Horror Unleashed Las Vegas

	Any visible hardware risked breaking the illusion, so the system had to feel as if it was never there at all.

Universal has brought its legendary horror brand to Las Vegas with a venue unlike anything the city has seen before. To make every scream possible, EPS was tasked with building the invisible backbone, a massive pipe grid spanning the entire venue, supporting lighting, sound, and effects for every maze while disappearing seamlessly into the darkness.

The new Universal Horror Unleashed Las Vegas attraction in Las Vegas has reimagined the haunted house an unprecedented scale. Rather than a single maze, the venue houses multiple fully developed haunted experiences under one roof, each packed with intricate hallways, layered atmospherics, and unexpected frights. Bringing these productions to life required more than clever scenic design, it demanded a structural and technical backbone that could invisibly support lighting, sound, and effects throughout every square foot of the venue. Across the venue, the scope was staggering. The build required 7,892' of pipe, 701 individual sections, and hundreds of custom connection points to hold it all together. It was a full-scale infrastructure project hiding in plain sight, quietly supporting the chaos below.

That responsibility fell to Entertainment Project Services (EPS), who designed and engineered a pipe grid system spanning the entire attraction. Unlike traditional haunted houses, where equipment is often hung piecemeal, this project required a continuous solution that covered each maze and room while remaining flexible enough to serve different creative visions. The grid had to align with the unique production demands of every designer, be structurally sound to handle heavy loads, and at the same time disappear from the guest experience. Any visible hardware risked breaking the illusion, so the system had to feel as if it was never there at all.

EPS' engineering ensured that the grid blended seamlessly with the architecture of the mazes while still delivering the structural integrity required for extensive rigging. The result is a technical framework that supports a complex mix of lighting instruments, atmospheric machines, audio systems, and scenic elements, all while staying invisible to the thousands of guests who pass beneath it.

Behind the scenes, EPS' fabrication team assembled 952 intersection brackets, 285 hanging lines and turnbuckles, and 597 welded standoffs and assemblies, each designed to fit the unique geometry of the mazes and themed environments. Every component worked in harmony to support the haunted houses, the surrounding cityscape, and the showcase bar, all while maintaining the illusion that nothing mechanical existed above the guests at all.

What audiences encounter is a fully immersive environment where effects emerge from every direction, without distraction or dead space.
