COMPOUND: Inside Scarefest’s Most Disorientating Maze

Everything you need to know about compound

If you've ridden Nemesis Reborn or Nemesis Sub-Terra, you already know the Phalanx — the shadowy organisation tasked with containing the alien creature buried beneath Forbidden Valley. COMPOUND takes that mythology somewhere considerably darker, and in doing so has become one of Alton Towers' most talked-about Scarefest attractions since its 2024 debut.

The Story

The premise is genuinely unsettling. The Phalanx have been busy on their latest project in a new facility just outside Forbidden Valley, and guests are invited inside to discover how the organisation's scientists have weaponised human DNA. Official materials warn visitors to mind their step, lest they become too involved in the experiments themselves.

The maze's best piece of writing is a genuinely sinister reassurance: you'll never be left alone inside the complex, because you'll be shadowed throughout by Phalanx Operatives — who are, as the official description puts it with heavy irony, there to relentlessly protect you and for no other reason.

What Makes It Different

COMPOUND breaks from Alton Towers' usual linear maze format in one significant way: it's built around multiple possible routes rather than a single fixed path. Reviewers have compared its design directly to Thorpe Park's Survival Games, though noting COMPOUND leans more heavily on physical theming and less on hands-on actor interaction than its Surrey counterpart.

That multi-route structure is what generates the maze's defining feature — genuine disorientation. Described in press coverage as an intense and disorientating attraction set within dark, claustrophobic labs and hallways, it's a maze designed to make you genuinely uncertain where you are and where you're going.

Be Prepared to Be Separated

This is the single most important thing to know before queuing. Multiple first-hand reviews specifically warn that if you enter as a pair or a group, you should expect to be split up — a deliberate mechanic rather than an accident of crowd flow. One reviewer's explicit advice to prospective visitors was simply to be ready for it.

It's also worth knowing COMPOUND permits actors to touch guests, a genuine departure from the standard no-touch rule most scare mazes operate under. Guests aren't expected to touch back, but this makes COMPOUND meaningfully more physically interactive than mazes like Altonville Mine Tours or Edge of the Forest.

Where to Find It

COMPOUND occupies a purpose-built maze building on Gloomy Lane, on the route toward Forbidden Valley — a location deliberately chosen to sit close to the Phalanx's own established territory within the park's wider ride mythology.

Worth Knowing

COMPOUND typically carries a 12+ recommendation, and requires a separate maze ticket on top of standard park admission. Given the group-splitting mechanic and permitted actor contact, it's worth considering carefully if anyone in your party is anxious about either — though for anyone seeking Scarefest's most intense, disorientating experience, it consistently delivers exactly that.
