ShadowLab opened on April 1, 2025 at Oosterhoutseweg 13 in Rijen, at the location where 'Escaperoom Rijen' previously ran the duo room De Kunstroof (some directories still list it under that name). Motto: 'where nothing is what it seems.' The core room is De Vermissing van de Kolonel, where you figure out what happened to Colonel Van der Vliet who worked at the real air base Gilze-Rijen (~200 m away) and disappeared after his wife's sudden death; there's also the large outdoor room RED ALERT! Reviews are positive (EscapeAll 4.5/5 from 7 reviews) and praise the passionate owners and how well the theme is integrated with the real surroundings. A nice marketing detail is the 'Rumors' blog that spreads gossip about the location beforehand. The décor is modest/low-budget and there are few published prices or reviews — it's a very young venue.
