Absolutely fantastic shooter. Great level design. Ferocious enemies. Coolest guns you will find in any FPS. All perfect brought together by a badass soundtrack and crazy fast gun play. I do not have a single negative thing to say about this game. Everything feels very balanced and thoughtful. Don't play it for the story. Play it because it's Doom and you know what you're in for.
Even though I'm kind of a wuss when it comes to anything remotely horror themed, The game stressed me and had me at the edge of my seat, but I couldn't put it down because I loved the gameplay so much. Trust me if you are even slightly interested in this, get it.
