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 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.


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.

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

The story of Half-Life continues in Episode 1, right after Half-Life 2. Gordon and Alyx have to escape City 17, but not before containing the Citadel Core.

The game is a lot shorter and doesn't have as much content. Over the course of it, you acquire all needed weapons to complete it. You will still fight ships and striders though. Puzzles are pretty much what you would expect from a Half-Life installation. Whole game can be completed using only the gravity gun, because you are always with Alyx and she's able to do the shooting instead of you.

Nothing new is added, except maybe a new zombie, no weapons, no vehicles, but it doesn't really matter, because continuing the story is more important. If you liked Half-Life 2, then you should also probably buy Episode 1.
