Total classic. Story-line is amazing. The music enhances the whole experience by a lot and I would recommend this to anyone who loves a good run-n-shoot ♥♥♥♥ ♥♥♥♥ up (screw stuff up) game. The puzzles are crafted really well and still holds up to this very day as one of the best FPS games ever. Avoid the Source port version of the game if you can, and if you want a graphically better experience, pick up Black Mesa.

If you're having issues with the music cutting out, download the Half-Life soundtrack from the Store page.
