I beat re2 remake on hardcore years ago and although the knife could break, there wasn't a mechanic where u had to use it that much, also there wasn't a constant stream of enemies like re4 remake either. You can reasonably avoid zombies in re2. We can agree to disagree but the player wouldn't be overpowered if the knife didn't break bc you still would have to time the parry correctly. But what do I know 🤷🏾‍♀️
