i didn't know what to expect when i bought this, but to date it hasn't let me down. with so many flash in the pants games out today where you lose interest real fast, this old standby keeps your interest from start to finish. with stylish graphics and excellent sound effects it will chill you and thrill you. from fighting your own kind to fighting far away aliens, you will be kept busy moving fast and ducking faster, never knowing what lurking in the next air vent or around the next corner. Half-Life is just an exciting game to play, once you beat it, you'll want to start over to do it again.
