The story of Half-Life 2 continues with Episode One, a must-have for people (like me) who can't get enough of Half-Life 2.

Dig deeper into the operations of the Combine as you venture through new areas. With 18 hrs on record I can say there's enough gameplay time in this episode to keep you from socializing for a few days ( ͡° ͜ʖ ͡°)

9/10

Half Life 2: Episode One is the direct sequel to Half Life 2, but is it worth the name ?

Half Life 2: Episode One begins as soon as Half Life 2 ends. We find ourselves in a bad place as the citadel is about to be destroyed and it's gonna take the entire city with it, so you need to escape before the city is destroyed.

This review will be incredibly short since this is pretty much Half Life 2, I'll just cover the cons and pros of the game.

I want to say this was a bit disappointing playing this episode. Apart from the final mission, the entire game is kind of boring.

The gameplay is the same thing as in Half Life 2. There's no change whatsoever. There's nothing really new here it's basically the same game as Half Life 2.

The story is still great. But I think the events leading into what is Episode Two are far more interesting than the entire story of episode one.

My biggest problem with this game is probably the story. The game is kind of slow in pacing and it's a drag and not to mention it's also incredibly short.

It took me 2 hours to finish the entire game. There's pretty much no replay value after that.

Overall my feelings towards this episode are still positive. This is as good as the previous Half Life titles, just the story is kind of boring, but apart from that it's a great game.

Final Rating:
7/10 - Play it

Milestones In Gaming Never Get Old


There is not a lot left to say about HL2. We all agree that it lifted the genre to the next the level.

I have to confess however that I haven't played HL2 Episode One at all during the last 9 years and that I did not even touch it during the last 4 years that I have it in my library.
THIS WAS A GREAT MISTAKE AND I REGRET IT


This 9 year old Stand-Alone Expansion of HL2 is perfect: story, characters, puzzles, innovation, action, design and even the graphics are still on a very high level and way ahead of some newer games. And it runs like butter...

New features like
VR or 3D Vision
lift HL2 in general into the new age of virtual reality, of gaming. I played it with 3D vision and had a great blast wandering through City 17, the Citadel.

HIGHLY RECOMMENDED!

If you have it in your library since a long time, but never touched it, never installed it - like I did. Do not wait any longer. 9 years have been enough. GREAT GAME.

-Quick Review-
Half-Life 2: Episode One was Developed by Valve Corporation and released 2006. Not much changed from Half-Life 2, this game is a continuation and starts right after the events of Half-Life 2.
http://steamcommunity.com/sharedfiles/filedetails/?id=520555541


-Detailed breakdown review-
Story: After the events that took place in Half-Life 2, Gordon and Alyx Vance are reunited and need to escape City 17. Unfortunately, they cannot escape before the Citadel's core detonates. So Alex and Gordon are forced to enter the Citadel to stabilize the core long enough for them to safely escape.
http://steamcommunity.com/sharedfiles/filedetails/?id=520555575

Gameplay: There are only two changes to the core game: First, Alex's AI has been dramatically improved, so she is more helpful and not nearly as annoying as most NPC's that simply repeat the same phrases and actions. Second, you start the game with the Gravity Gun, which is utilized both in combat and puzzle solutions.
http://steamcommunity.com/sharedfiles/filedetails/?id=520555594

Achievements: There are 13 achievements in Half-Life 2: Episode One. Five achievements are unlocked by just completing the game, the rest are achieved by special circumstances. (like... “beating the game firing exactly one bullet”, “not killing any stalkers”, or “killing an elite soldier with his own energy ball”)
To be honest, these achievements aren't very bad, this was a relatively easy 100% completed game, compared to others games.

Price: Half-Life 2: Episode One, is priced at $7.99, unfortunately the game is very short, and this price is a bit high for the amount of time it will take to play through the game. (You will probably spend about 5 or 6 hours to beat it)
A far better alternative, is to purchase The Orange Box for $19.99, you will purchase: Half-Life 2, Half-Life 2: Episode one, Half Life 2: Episode Two, and Portal.

Conclusion: Story: Still very good, but unfortunately much shorter then Half-Life 2. Gameplay: Pretty much the same as Half-Life 2, the only difference is you use the Gravity gun much more, and much sooner. Achievements: Straightforward, fairly obtainable 100% completed game. Price: Over priced, wait for a sale, or purchase the Orange Box for the best value.
I recommend this game to anyone who played Half-Life 2 and wants to continue the story of the Freeman...

Let's be honest. Episode One is very short compared to Half Life 2, but it has a greater frequency of action events and happenings. I really like the speed it starts with and they keep it until the "end".

Solve puzzles. Let the woman grab a gun and take care of the killing part of the game for you. Don't let her die or you won't make it out alive!!! I like it, I sure like it that way :)
