It's more Doom Eternal and that's great! Really dig most of the additions here - the enemies, hammer, and the grappling hook platforming are all great. There's now so much variety in the encounter design that you never know what to expect. Also the final boss is extremely fucking funny.

I do have a few minor gripes though. The new prowler is the worst thing in the entire game, but they use him pretty sparingly so it's not a huge deal. The levels feel a lot less exploratory than the stuff from the base game which is a shame. Also the story kinda blows, I enjoyed the over-the-top comic-booky bullshit from the base game but something about the tone feels off here. Maybe it's a symptom of the antagonist being a guy instead of an AI or a giant demon, but it feels goofy in the wrong way.

Overall though I'd say that if you loved Doom Eternal then this and the first DLC are definitely worth grabbing, just expect a little more inconsistency than the base game.
