I kinda disagree with your DOOM statement. I assume you’re talking about the Carcass or the shield zombies. They may stop your momentum when you first encounter them, but the game (for me) is all about recognizing each enemy in a flash and quickly dispatching them. It’s not like the shield is super hard to bust for the zombies, just a few plasma rifle shots and they blow up the nearby zombies too. For the carcass, a quick blood punch will one-shot them. Once you’re able to recognize the enemies and their weaknesses at a glance, they become part of your momentum, instead of stopping it.
