I can't hear as well on my left ear and I don't want things like this in my games, and it's not as it was included for people like me, either. And the complaints are more than just the inclusion of wallhacking itself, it's also how poorly it's integrated into the game. You keep repeating that it's optional, but we don't know if the game was designed around this crutch. Maybe it's in the game because the sound design in the game is not clear enough for you to detect enemies on your own. There is no leaning, you can't really see around corners, either. I don't like wallhacking and I'm not out to make a game artificially harder than it is. So basically I'm screwed. Some of us, I guess, had different expectations based on what was shown last year. We were shown that the game goes to the point where you can't pause it while crafting or looking through your inventory. We even saw Joel pick up ammo by picking the actual weapon, getting the ammo out, and then discarding the weapon.
And now, wallhacking. Yeah. People are going to complain, sorry.
