It's been a while since I finished it, but man this game just leaves me with mixed feelings. As much as I loved the story, characters and moments (one of my favorite games from a narrative perspective in a loooong time), I almost equally disliked the actual gameplay. Really sad since I really liked the gameplay of the first Machinehead Wolfenstein.
It's generally way too hard to play as a shooter, borderline broken (at least on anything above the very easiest difficulty), providing basically no feedback that you're getting hit, unless you keep your eyes fixed on your health bar at all times. I'm as tired of the generic red bloodvein borders illustrating that the player is hurt, but man I missed something as stupid like that when playing this game.
On the other hand then it's also just not tight enough as an actual stealth game, and honestly most encounters feel like they're designed for stealth up until a certain point, where they want you to start playing more aggressively. The first game found a much better balance in my opinion, functioning primarily like an excellent shooter where stealth was a fun way to mix things up, but not actually required. Here stealth seems strongly encouraged, but without making it a better stealth game in the process. It's a damn shame.
Anyway, with all that said I still recommend the game, the story and the places this thing goes to is simply that good. And yeah, the first couple of hours are the worst gameplay wise, but it does get somewhat better (and so does the story).
