The first thing you’ll notice about Doom Eternal is that the combat has been revamped from previous titles. You no longer have a huge supply of ammo at your disposal, but instead you have to carefully calculate and evaluate every fight you enter.
Doom Eternal: IGN Review vs. Reality
This may seem like a turn-off to the chaotic, fun aspect of Doom, but in a strange way the limited supply of resources challenges you to get better at the game. Doom Eternal always keeps you on your toes, and speed is the best strategy to use in this game. If you're fast enough and have a good understanding of the map you're on, defeating enemies is more like solving a puzzle.
Doom Eternal brings out your deepest, chaotic desires. It feels good to be in touch with these basic survival instincts, as you spend the first few hours running from demon to demon, killing them for resources, finding cover, or simply exploring. The best thing about Eternal is that you are rewarded for everything you do, and multiple playstyles will enhance your experience.
The main difference you’ll encounter in combat is that each weapon serves a different purpose, and finding it is half the fun; once you learn where and how to use a specific weapon, you’ll be wreaking havoc like you’ve never seen before. Hordes of demons will be turned to ash in the blink of an eye and controlled with perfect mobility, and you’ll become a demon-killing machine that knows no bounds and unleashes a fury like hell has never seen before.
