This is a fun experience to do with the whole family. We were 2 adults and 3 teenagers (13, 15 & 17). The VR is immersive and more realistic than a home VR, as you actually walk around a warehouse to move around in the game (free roam), and you're holding and pointing a "gun", not a PS controller. The graphics are good and fluid, and the game is challenging but achievable. The in-game instructions are in French so some language skills would help, but not essential. The staff were also friendly and speak English very well.
We came out sweating and buzzing with excitement and wanted to do it again!
Some negatives:
As with all these VR games everywhere, it is expensive (25-30€ per person, so 125-150€ for family of 5). Due to time taken for pre-brief and kitting up, actual game play was probably only 30-40 mins. Our avatars were a bit glitchy, our arms would disappear every so often, and one player was invisible the whole time. For a while she couldn't see anything, so we had to pause to get help, which took away from our game time.
It is great fun though and worth trying.
