Tried it out. I can't say I'm a DOOM super fan or anything, but this one just feels odd. Not bad, just different. For one, it seems a LOT easier. I'm not playing on Nightmare or anything, but I'm judging it on par with the other games at the same level, and so far it doesn't have the same "enemy around every corner" type vibe as the previous installments. A lot of wide open flat planes with cannon fodder to obliterate, where maneuverability is not hampered by any tight spaces. The shield and melee attacks also feel a bit OP. Parrying is almost too easy(at least on the level I'm playing on). Seems like you can parry shit from like ten feet away. I figure if you're in a bind with those types of projectiles coming at you, you could just spam parry and be fine.
That said, it is a power fantasy, and it doesn't fail on that aspect. The weapons are great and all have a unique feel to them, and the game does force you to mix and match with different enemy types, so you don't get too reliant on one or the other. The results of your blasting and punching never fail to impress, with it's spectacular gore effects and 'splosions. The story is whatever, but they seem to put more emphasis on it this time out, where it can start to feel a bit like COD where you go from shooting gallery to cutscene.
Anyways, I'm probably not the best judge on these games, but that's what I've experienced so far.
