Half-Life 2: Episode One is a great continuation of the story from the base game of Half-Life 2. You pick up right where you left off, in the Combine HQ, otherwise known as the Citadel. It's fairly short, ranging anywhere from 2.5-3.5 hours in length. Now, let's see how this Episode differs from its parent game.

Episode One, in my opinion, is slightly more focused on storytelling than the original campaign. Please don't get me wrong though, as the gameplay was still heavily featured, with some menial improvements as well. As explanation for Episode One's extra focus on narrative progression, I'd say that, if you pay attention, you'll have a solid amount of your questions from the previous games answered in this expansion. In the way of gameplay improvements, I'll simply say that there were some nice new mechanics and a little bit of gameplay refinement. Another great difference was that you spend almost all of your time with Alyx in Episode One, and she really becomes fully fleshed out and even more likeable than she was already. The last difference I noticed were the faintly improved graphics in the form of lighting and reflection, as HDR was present in this episode, but was not in the base game. All in all, Half-Life 2: Episode One makes some minor enhancements across the board to an already wonderful game, all the while continuing the plot effectively. Other than that, the majority of what was stated in my review of Half-Life 2 (the base game) is still true to Episode One too. It’s of the same quality and thus deserves the same personal rating I bestowed on its predecessor.

Personal Rating: 10/10

half life 2 episode 1 is for sure a good episode. it follows the events of the last game from the exact spot half life 2 ended. Gordon and Alyx find themselves having to escape city 17 and help as many as you can get out. its overall pretty good, not the best, its not as strong as Half Life 2 and episode 2, but if you want ot skip it, you can if you want some good gameplay because this doesnt add anything new aside from the special gravity gun upgrade which i believe was shown around the end of half life 2. the only reason to play this is for to continue the story and it shows us 2 new enemies, the stalkers along with the zombie combine which are called "zombine".

like i said, not the best thing, 2 new enemies and 1 isnt really classified as an enemy even. all it does is continue the story and add a little escort mission, the nice thing is, Alyx does do more than she did in the last game, so thats a nice touch, but if you want, skip this if you arnt looking for story (which is kinda stupid considering that, well, half life has a good story, that really showed up in 2, because the original didnt really have story when you think about it)

It's a great game, but I have one complaint: It's too short! The only way to make up for this (besides updating it) is making Episode 3!!!!!!!!!!!!!!!!! NOW!!!!!!!!!!!!!!!!!!!!!!!

It's okay I guess. Focuses more on the Gravity Gun than the earlier games so you'll remember using it more, especially with the One Free Bullet achievement. Combat and puzzles are alright as usual and the end fight is pretty good.

Short little expansion from Half Life 2. Short enough to actually merit the achievement of not using any guns.
Pretty much picks up where HL2 ended and pushes the story far enough to set up some filler detail for the next bits.

Visual, audio and gameplay are great! Leaves you with a lot more questions than answers but thats what HL does best.

If you liked HL2, this is the next bit. Think of it more of a DLC... Gravity gun for the win!

I recommend this mostly because it's easy to get at a sweet price. If you like being the lone hero, against the world, then too bad, because Alyx Vance will hold your hand throughout this entire mappack. Er, I mean "Episode". Yeah.
It's not quite as bad as I just made it sound though. It can be pretty fun. But you might get sick of everyone telling Gordon what to do.

They gave me more Half Life 2, with more Alyx and better graphics. I took it with pleasure. And wanted it to be so much longer because the gun play and physics are so much fun to fool around.

Gawd I love this series.
Everybody should give this game a chance.
Those people who never played it or played it for like 10 minutes don't know what a game needs.
Sure many people don't think the same way as I do, but c'mon:
-Playing the game 10 minutes doesn't give you the experience of this series
-Playing this game without a gamer's heart doesn't give you the feeling of beeing Gordon Freeman.

(Yes this all sounds weird, but it's my opinion.)

its a good but short (around 4 to 5h to complet) sequel to the previous hl 2, the story takes off after you blow up the citadel and your main objective is to escape city 17 and this time you will get a closer look at the stalkers and the strange alien like creature that you see in hl 2 and of cours it will leaves you with more unanswered questions .
the graphics, sound effect and the gameplay are just like in hl 2 nothing has changed except for the source engin i think ( it looks a bit better visually then hl2) + there is 13 easy achievements

And you have to evacuate the city's residents and escape yourself. But now that Dr. Breen has fallen, what are The Combines suppose to do now?

I always thought "Half-Life 2: Episode 1" was a strange name for the continuation of the plot of Half Life 2 and a little undeserving in my opinion. After the hanging thread in Half Life 2, you progress the plot as Gordon Freeman once more to escape City 17 with Alyx Vance before it's reactor goes critical. The game itself can be beat in a little under 2 hours, but it's a DLC so I'll let it slide. Oh yeah: Cliffhanger ending- Check.

Pretty short review; not much to say here.

I rate Half-Life 2: Episode 1 with a 7/10

Wait for it to go on sale before you buy it; I don't think it's worth $8, but the choice is yours.
Until next review!

Not much to say about this one. Half-Life 2: Episode One is of course a continuation of the story in Half-Life 2. Fundamentally it plays the same as Half-Life 2, though the graphics are slightly better and this time you have Alyx as a partner for most of the game. As an episodic game it's also shorter than Half-Life 2, but if you liked that game, you'll probably like this.

A short-lived but important part of the Half-LIfe 2 storyline. Don't skip this, it may be shorter than the other two but it's still very much worth playing.

Set after HL2, this epic episodic followup has you involved in a desperate escape from City 17, and still holds up great almost 10 years later!
