Short version: Buy this game on a really good sale. Like 75% off or more. It's not worth the base price.
Long version:
I really wanted to like this game. It was recommended to me a long time ago and I just barely got around to it. Aside from two missions, I really couldn't get into this thing. I felt immensely disappointed at every turn and there were some scenes that permanently damaged my opinion of the game. We're talking zero chance of redemption kind of stuff. I'll mark those with spoiler tags but I think you should read them even if you haven't played.
Wolfenstein 2 feels nothing like the other Wolfenstein games. It's hammy, imbalanced, and unfulfilling. This game suffers from many different issues, but by far the worst is its characters, so that's where I'll start.
I could not find myself to care about anyone other than William, Anya, and Fergus. Those three are the only characters I even cared for. Everyone else was either grossly underdeveloped or painful to listen to. By far the most painful being Grace. Her prideful attitude and self serving nature made her borderline infuriating to have as a regular member of the cast. It did not feel like she deserved to have the position she held in game. Once she was introduced, I began my short wait for the game to end. Some of the characters became unintentional stereotypes which wasn't fun to watch happen. It's fine when it's intentional, but when it's not, then the stereotype is all the character becomes. All the characters were so goofy too. The only sane one being William. Fergus was close but his arm just hurt his character because it was used too often as a gag.
All of the seriousness of the characters was thrown out for Reddit tier humor remnant of an immature man-child putting whatever they wanted onto a writing board.
The writing in general is awful. I know this is a game about killing Nazis, so it's meant to be a bit over the top. But man, this game does not know a thing about subtlety. Things just happen for the sake of them happening. There is a point where you could replace the Nazis with any other group and nothing would change. It became mindless violence just for the sake of it. There were so many scenes that were so unnecessary. The previous games had meaning in their choices. Significance in their cut-scenes. There was goof factor but when the game needed to be serious, it managed to do it. Somehow, this game does not know how or when to be serious. It killed it at the start, but horrifically failed at the end. Scenes that ruined entire moments because they just had to.
I almost wanted to rate this game as a middle thumb but then one particular scene finalized my negative view of the game. This scene is right at the end of the game so I'll mark it as a spoiler. At the very very end of the game. There is a scene where Will's pregnant wife Anya throws a grenade at the Nazis and then ducks on top of Will to shield them. Afterwards, she tears her shirt off and dual wields machine guns while blood rains down on her naked body. This scene sucks. It does nothing. It doesn't add to either character's development, and it adds nothing to the game. It's just murder porn. Unnecessary, and undeserved. There are other scenes like this. Ones that are just violent for the sake of violence. They feel like self insert revenge fetishes played out through the game's characters. There are other scenes that also just go on for far too long.
Unlike these scenes, the game itself does not go on for very long. My whole play-through including two assassination missions, was 10 hours long. That's about eight hours of story for a $40 game. The price is absolutely not worth it. I'm so glad I got this on a big sale because I would've been borderline depressed if I hadn't. The missions are all really short. The level designs are cool, but overly confusing. I got lost in places that I really shouldn't have. The gameplay itself is really bland. For a violent wave shooter, there isn't a lot of variation in what you can do. You either shoot with one gun or another. Dual wielding being the only fun way to use the guns. Upgrades felt pointless and so did the contraptions after the first mission they were introduced in. The movement was also really shaky and made my head hurt sometimes. I considered streaming it to friends but noticed that you could hardly tell what was going on at all during action sequences. Overall performance was lacking. I've never had a game stutter so badly when set to low settings. And I have a powerful PC too. Easily could've ran ultra settings but I couldn't because the game wouldn't work properly with them on. Some missions like New Orleans were almost unplayable because entering a new area would freeze the game for a moment while all the particles and models loaded. This is ridiculous because the levels are so short anyways,. Why am I taking even a few seconds to load an area as big as a CoD map?
I really couldn't get myself into this game. At every turn, they took a potentially great story and ruined it. This is the first time in a long while where I've had a non-multiplayer game be a hard negative for me. This just sucks and I regret spending my time on it. Maybe it's just not for me, but this doesn't scream Wolfenstein at all. It feels more like hippie garbage akin to the terrible Saints Row reboot. Don't waste your time on it. Or if you do, wait for a big sale. A dollar per hour played feels fair for it. So I'd say $10 or less is a fair price.
