To preface this, I have not played the original game. I am also a huge survival horror fan, I've probably played almost every main release in the genre from the last 20 years and a bunch of indie releases too. I also played the game on Hard Night mode, with additional playthroughs on the highest difficulty with unlimited ammo and no mask revives.
I really enjoyed this game, but it is far from perfect. There's a lot of really great things in the game but also a lot of frustration and places where the game could have used a bit more polish.
Combat: This was my main gripe with the game initially. The first few hours combat did not feel good at all. There were a couple of reasons for this: The guns felt they had no weight, enemies don't really react to being shot and when they do it doesn't feel satisfying. Multiple times I would have 2-3 enemies in front of me within touching distance, and they would eat a shotgun blast like it was nothing. One might fall down but the rest were good to go. The sound design of weapons is also subpar, this adds to the feeling you aren't really doing anything.
The other side of combat is the melee attacks, and man... This was executed poorly. Melee only feels useful in very niche situations. An enemy goes to the ground and you stomp them? Great. You try to stomp them a second time when they are still getting up? You'll miss and take damage. You want to punch an enemy? You MAY hit them, but more than likely you'll see the punch connect but do no damage, instead you will get hit. This system just felt super rigid. You are playing the games game, not your own. You will play by it's rules strictly and to a T or you'll suffer for it. One of the things that made SH2 remake so good was it's combat being so adaptable. You could come from shooting, to dodging to melee so fast to react to what was going on. On target attacks always connect, dodges were tight and effective and a quick gun shot could end a fight fast. SC2 feels like it saw this and thought 'lets do that, but way worse!' Speaking of dodging, the window can be very tight and I've directly seen enemies changing direction after you dodge. The deep ones were the absolute worst offenders, executing a perfect dodge only to see them changing direction in the very last millisecond to get a hit off on you felt cheap.
All that aside, once you start getting more weapon choices the game picks up. None of the guns feel particularly satisfying to use though. And I think I know why this is. It's the enemy weak points. I personally think the weak points might be my least favourite thing in the whole game. This isn't Zelda with the boss having giant eyes, it's survival horror. You're supposed to be fighting tooth and nail to make progress, not waiting around for the enemies to provide an obvious weak point. Most of the time it felt like targeting anywhere other than the weak point was a waste of time, very little damage or stagger occurred when targeting none weak spots to the point it felt like I was throwing precious resources away. Again, you are playing by the games rules and there is absolutely no room for deviation from that.
Audio: Audio is something I don't really notice in games unless its very good. SH games have this down to a fine art in my opinion. SC2 however? It's ok. The general sound effects are pretty nice, the enemy sounds are decent and creepy at time. It's all marred by the terrible sound quality though. Everything sounds muffled besides the voice acting. I checked the settings and could not find a way to fix it. Changing from headphone to speakers, which was the default for some reason despite me using speakers, helped slightly but it was still pretty bad which was sad. Voice acting is also just ok, nothing standout but nothing bad either.
Graphics and design: This is where the game absolutely SHINES. This game has phenomenal atmosphere and draws from it's source material very well, if a little conservative at the same time. The locations are all straight out of a Lovecraft story, the Hospital and Fish Market were both fantastic.
Story: Again, this was just ok. The main story is pretty light honestly, and while the stakes were high it never really felt that way. A lot of the time the characters are urging you on in a rush, but I never felt that much urgency personally. The side characters though? Very engaging. I really like the characters we met along the way, their back stories (which arguable were only really fleshed out in Ex Oblivione mode with the extra notes) were very good and I wished we had more time with each of them. I was far more invested in what was going on in the Hospital outside of our main characters objective, and with Ma in the markets personal history than I was with anything main story related.
If I had to give this game a score I'd honestly have to say 7.5/10, with strong leanings to 8. The game IS very good, it just lets itself down in a lot of ways. None of the negatives are so bad that I would say don't purchase the game, but I would also say unless you are a modern survival horror fan you're best waiting for a sale. Even as a fan of the genre, it is very rough around the edges, but if you can stick it out there is a truly great game at the centre of all that.
P.S - The DLC is also phenomenal, and arguably way better that anything in the base game (Hospital area is a close contender though.) It gives you a nice reward for the main game too. It feels like this DLC may have been completed last, because it overall feels much tighter than the base game. I'd recommend this a lot.
