That's like one of the key selling features of the game. Great experience that also scars you for life.
The worldbuilding in Half-life was so good. You weren't a character walking into rooms and enemies would attack you, like Doom and Quake. There was a big event happening, and you were just a part of it.
It was on par with my first playthrough of the original HL so many years ago.
