It's baffling how out of the classic Doom games, only 1 is good. 2 Is too big for its own good, with a scale that does not fit the gameplay, and this one either falls into the same trap (it even just reuses some Doom 2 levels) or shoots itself in its own foot with new design approaches.
The shotguns have worse and lifeless reload animations, the overall redesign of a lot makes it feel like a cheap knockoff more than anything else and the atmosphere does not mesh with the game.
Levels are more confusing than ever, and they decided to adapt something from Quake - where you have to shoot buttons sometimes in respect to a 3D environment. Only you cannot look up and down like in Quake, so the game may ask you to find a spot where you match the height of the button and then shoot it. Good luck even figuring that out after wandering the empty halls in confusion for a while.
Rounded up with a final boss that is either ridiculously difficult or easy depending on if you found some secret levels. Seems like it is only a balanced fight when doing one or two of the three secrets, as otherwise you are either both overwhelmed and weak or underwhelmed and overpowered.
