It is not always clear what the correct choice in a quest should be, which is a good thing, really. At one point you’re given a choice of either blowing the famous Chernobyl radar or keeping it to use it yourself. And it’s not clear why blowing it up would be a good thing, except your wife hated it. So that’s what I did.
Found AK47 quickly enough in the Pripyat Port. Even with an upgrade. With it, and the upgraded shotgun against “zombies”, the game becomes more shooter and less stealth. Which is good, as the stealth in this game is not so enjoyable. There are “alert cones”, that point to the enemy that is suspicious of you. But that’s it. Not only you can’t see through walls and don’t have a radar, it’s also very hard to distinguish enemies from their surroundings, and since they all wear masks, it’s hard to tell which way they’re looking either.
“Biometrically locked weapons” are a common trope in games explaining why you can’t just start picking weapons from dead enemies, and need to make do with what you have, like crafting them. But I’m not sure why the authors even bothered, as weapons seem to be quite plentiful anyway.
