You'll be disappointed if you're looking for "more DOOM 2016"- Eternal is a different beast entirely. Feels much more like a realtime first person puzzle game than a mindless arena shooter. Knowing enemy weak points and what guns do the most damage to that specific enemy + micromanaging ammo, health and armor is a BIG part of Eternal's gameplay loop. It's very good, but it's quite far removed from 2016 in terms of gameplay.
