This was a good and fun experience. Even though this is a tech demo for Source's HDR, This was still was a nice and fun demo. The commentary mode was good as well. Overall, it was nice game to play for half an hour.

Man...Where do I start?
To begin, This game is absolutely legendary and it was extremely fun to play through it again. The gameplay, story, characters, combat, visuals, writing and the level design are all incredible. This is still my favorite Half Life game.

It was a good game. I like how they expanded Black Mesa and the new mechanics that were added. The story was good, the gameplay was fun in places but I wish some of the new features were expanded upon and some of the enemy encounters were not fun.
