Very fun to play through but not as good as the prequel, you spend half of the 3 hour long game underground fighting zombies, and thats about it 8/10

♥ I WROTE THE SAME REVIEW AT HALF-LIFE 2 ♥

I was playing this only from google and Kickasstorrent, because in 2007/2008 my mom wouldn't let me to buy video games.. so
*DOWN ARROW*
This game is my whole childhood.
I've been playing this from like 2007/2008 when i updated my pc so i can play newest video games, or with better graphics because , at that time that shi&ty PC that i have, was something great for me.
the Half-life Franchise is a part of me and my childhood.
I still don't know why I love this game but is so different from the other games.
THIS GAME WAS , IS , AND IS GONNA BE MY FAVOURITE GAME.
half-life 1 }
half-life 2 }this is my
half-life 2 episode one}gaming family <3
half-life 2 episode two}
AND YES I'M STILL WAITING FROM 2007 FOR HALF-LIFE 2 EP. 3/HL3 TO COME ON STEAM, SO GABEN PLS.

Gameplay wise - it has some great moments; including a standout section in which the player directs Alyx Vance's fire via a flashlight.

Unfortunately Valve became sloppy with this expansion pack - opening with a deus ex machina in the lazyest manner poosible.

The scripted sequences become contrived "look at this" moments with Alyx Vance spelling everything out for the player or repeating "oh my god" or in general, gasping at anything and everything to give a foiced sense of drama.

Basically - it's more Halflife 2, but not as good. It's still a great - great game. Better than 90% of shooters out there, but pales in comparison to the main game.

Would still recommend it.

Half-Life 2: Episode One continues the story of Half-Life 2 with another adventure of Gordon Freeman and Alyx. The story picks up right away after the original game and offers more of the same as the original. There's nothing really new to note here besides some new enemies and a level that puts good use of the flashlight; you also have Alyx by your side the entire time - which allows for some unique gameplay, such as not firing any bullets and only using the gravity gun. Episode One is somewhat short, I was able to complete the game in ~3 hours.

Oh my god! I had never played any of HL2's sequels, but damn, have I missed a lot!
This game is epic!

It's a 3 hour long ride that's so wild and intense that makes all other action games feel dull and flat.
But... what am I talking about? There are no other action games! There's only one king, and Half-Life is his name.

A must play!

After playing this game, and the first one, I felt a great sense of achievement, for Half Life 1 and 2 are brilliant games. Definately recommended those who haven't come to playing it.
