That was just one section of the game. The game is still as good as it was back in 2004. Not following the tedious the gameplay. Its darn good imo, with a few overpowered weapons that kinda break the game. But yeah the level design, story, well written characters, humour and action. Its all there.
Then again massive fan of Half-Life franchise. I replay the HL games from time to time. One and two are timeless classics imo. I can't think of any older FPS I like to go revisit. Maybe Duke Nukem 3D for some nostalgia and some luls
