This game is a mixture of Doom with some Guitar Hero aspects. The main idea is that you time your attacks to coincide with the music beat. The game physics work pretty well and I never had the game crash on the PS4 version. The major issue is a particular trophy tied to the challenge levels. It's a simple completion trophy yet it is glitched. Most DO NOT get this trophy to work. I'm it's a known issue with the developers and they in fact patched the PS5 version. They left out everyone the purchased the PS4 version. This is not an isolated case when it comes to devs picking and choosing whether they fix the game that you had to purchase. Unless people stop supporting these game studios, these issues will continue and our game quality will continue to plummet. Make a list of these studios and don't purchase their games.
