Fairly sure they use HTC vive which seems to be the standard for overpriced VR experiences. It’s mostly fun to play in a group I think. But the actual games are very underwhelming - they feel like tech demos. And on top of that the staff never sets IPD or anything so unless you adjust it yourself things can be a blurry mess. The experience of a game like Alyx on the Index/Quest is about 100x better.
