Not the person you're replying to, but Doom Eternal gives most enemies some hyper-specific weakness that requires you to switch to one specific weapon to deal with them. Most fights are huge swarms with multiple different types of these enemies so you have to identify which ones are the quickest to deal with/biggest threat, and then deal with them one by one. They also doubled down on the resource management with multiple types of grenades, the sword, and flamethrower in addition to the chainsaw so you need to constantly monitor your cooldowns and leave weak enemies alive to farm HP/ammo/armor if you get low. You do this all while bouncing around the arena at 100 miles an hour. Eternal is the only shooter I've ever played where I feel mentally exhausted after only a mission or two.
