Now the horror reaches new heights with Widow's Walk, the first-ever expansion for the critically acclaimed board game Betrayal at House on the Hill. The house is expanded with the addition of twenty new rooms, including the roof, a previously unexplored floor. Also in its halls you will find new monsters, items, omens, events, and fifty brand-new haunts, penned by lead developer Mike Selinker's all-star cast of contributors from the world of gaming and entertainment. In Widow's Walk, terror and panic are taken to a whole new level.
Enter if you dare. Exit if you can...
The Avalon Hill announcement lists more than forty people who are credited with contributing to the haunts included in Widow's Walk, and the list includes names that you'd expect to see from the base game (Glassco, Selinker, Rob Daviau), names of other board and card game designers (e.g., Paul Peterson, Justin Gary, Liz Spain, Christopher Badell, Jonathan Gilmour, Elisa Teague), and names that you probably wouldn't have expected (e.g., Adventure Time's Pendleton Ward, Feminist Frequency's Anita Sarkeesian, Cards Against Humanity's Max Temkin, Depression Quest's Zoë Quinn, The Doubleclicks' Angela Webber).
As for the compatibility of Widow's Walk with the existing editions of Betrayal at House on the Hill — both the original from 2004 and the 2010 second edition — Michael Robles, Community Manager at developer Lone Shark Games, has noted on Reddit that the expansion "is compatible with all editions".
