Stranger Things VR is an excellent little insight into the overall show, giving an explanation on how Vecna escaped from the Upside Down and showing his experiences there.

That being said, even speaking as someone only two chapters into the game, it is both disappointing and sort-of impressive.
Movement around the Upside Down feels quite fluid once you get the hang of it, however there is absolutely a learning curve as it feels finnicky as a first time player. While the game obviously scales back Vecna's abilities and general strength, you still get a decent feel of how it would be in his weird, goopy shoes as the powers demonstrated feel fantastic to use.

However, it is quite easy to get lost in the Upside Down. One particularly cool feature is being able to travel into other creatures' minds, however the lighting is all over the place, so much so that you start the game being unable to see details on a table due to how bright the area is, yet in these areas, it feels like a pitch black room where you're essentially crawling around on your hands trying to get a feel for an exit.

Overall, I've been rather enjoying my time with Stranger Things VR, but it is absolutely flawed. The price range is kind of accurate as paying more than £25 for this would definitely leave the feeling of a massive hole in your wallet.
