Pre-Release Review
Episode One picks up the story right around where Half-Life 2 ended. Alyx and Dog are looking for you, and your job is to get the hell out of City 17 before it blows up. There are a few enhancements to the gameplay, some new enemies, and a superb storyline that continues to expand the Half-Life universe. A must play if you are a fan of the series, or if you're looking for a quick shooter. The game itself is not long, but packs a punch in the short campaign that you play.

Not quite as good as HL2 but very much worth a go.

ever since playing through Ravenholm in HL2, i thought, "I'd really like a game where i have to use the gravity gun the ENTIRE TIME". and behold, HL2E1 was brought down from the heavens upon me, and a task was bestowed: to fire one single boat through the whole game
