Half-Life 2: Episode One begine right where Half-Life 2 ended, and continues the story of Dr.Gordon Freeman in City 17, however, this time, the priority remains to escape the city following the events of Half-Life 2.

With updated lighting and AI for deuteragonist Alyx Vance, and expanded usage for the Gravity Gun, Half-Life 2: Episode One continues Half-Life 2's usage of advanced graphics, physics, music and writing to create a game that is both rich in gameplay, plot, and emotion. Like its predecessor, it uses training techniques to allow for a more fluid experience, and utilizes the game's physics engine to a full. With excellent performances by its cast, it's able to greatly explain the story of Gordon and Alyx escaping City 17.

With an excellent soundtrack composed by Kelly Bailey, the game becomes even more action packed, and the act of blasting zombies in an infected hospital with a shotgun becomes far more enjoyable, and the scene of fighting infected Combine soldiers in the underground becomes more threatening.

The game also includes Developer commentary in the form of a commentary mode that allows the players to listen to the developers' thoughts on everything from map design to character and scene writing, and includes all variant of Valve Employee sharing their thoughts on the game.

If I had to say I had any issues with the game, I'd have to say that it's fairly short, while Half-Life 2 is around 12-15 hours long, Episode One is around 5 hours long. That's not to say it's a bad game for that, though, as the story and game runs at a certain pace that allows for it to be enjoyed to the fullest; Replaying the game with the knowledge of how short it is doesn't damage or reduce the enjoyment of playing it, as Valve injects a great deal of fun into the game so there aren't many moments or time that is wasted, and every minute is used to its fullest.

If you enjoyed Half-Life 2, and want more, I greatly suggest you buy the Half-Life Complete Steam bundle, preferably during a Steam Seasonal Sale. The bundle consists of this game and every other Valve-released Half-Life title, and is an essential for a fan of Half-Life.

A great follow up to Half-Life 2, expanding the story, and keeping the excellent gunplay while making things fresh and new for those who have played the games before. A modern classic that deserves a good playthrough, or two, or more.
(It is pretty short though)

Half-Life 2: Episode One 1 was released a bit over 8 years ago, as the even then long-awaited expansion of the original, critically widely acclaimed game. Since it is part of the Orange Box, the Half-Life 2 Complete Edition and the Valve Complete Edition, chances are great you already own and have played the original Half-Life 2.
The good news: Episode 1 continues on the high level of level design and gameplay the original had set. There is however an important shift in focus, as the greater part of the game is played alongside Alyx, Gordon's female companion-in-arms. Alyx happily stands her own against the enemy hordes and doesn't need any sort of "babysitting" games wtih less well developed AI sometimes call for. She's been updated graphically as well (looking even better ;-)) since Episode 1 makes use of the High Dynamic Range lighting effects first tried out by Valve in Half-Life 2: Lost Coast. However, compared to that playable tech-demo, environments in Episode 1 are a bit disappointing and don't always offer the best opportunities for the upgraded engine to shine. There are no wide-open vistas, and although the opening level in the Citadel is impressive, it also has a sort of repetitiveness that comes to the fore now and then.

On the other hand, gameplay-wise everything is as top-notch as it was in the original game, and the fact that you play alongside Alyx offers some interesting opportunities. There's even a Steam Achievement called "One Bullet" which gets unlocked by playing through the entire game (!!) using one single bullet. The rest of the kills/actions has to be made by using the Gravity Gun, which gets an upgrade during the early part of the game. This calls for clever thinking, and I tried to get it, only to find myself missing the shooting action after a couple of hours ;-).

All in all, Episode 1 is a good to very good expansion, continuing the story of the original game in a logical and interesting way. There's no reason at all not to give it a shot (...) when you've played the original Half-Life 2.

Overall rating: 8/10
