Too much thinking for my liking. You need to juggle all the different weapons that are most effective on so and so otherwise you're fucked. Also a lot more storytelling, which was... fine? But, rereading my negative vote on Steam, was told using the worst possible UX/UI.
I recall feeling like they had this perfect game, but then somehow, someone decided to hand it over to Bethesda for a last pass because, no, it's too simple.

Eternal's difficulty comes from how many guys it throws at you. Sometimes I just felt like I just made it through a tough battle only for a second or third wave of enemies to show up. It's like Doom turned up to 11, but 10 was already plenty for me.
