Half life is a great fps, it didn't age poorly in most as pects imo and i like the shooting more in here than in half life 2 and it's episodes even tho the fisics stuff were very fun to play around it.

Some chapters of it can be a bit boring like "on a rail" and "xen". but most of the chapters are very fun with the enemy encounters and puzzles you'll have to go through.

The story is very interesting and the moments it has like the giant tentacles that hear your sounds can be very memorable, enemies can give you a hard time but the game isn't terrible difficult, half life sure deserves to be a classic and remenbered for all it did to fps at the time it came out.
