Re-enter the Half Life Universe and revisit City 17 in the time before Freeman, in this fan made single-player mod. The Resistance is threatened by a decisive Combine assault, and as a wanted Resistance member you will need to fight to escape from the Combine's clutch. At the same time, a mysterious force is working towards ends unknown...

10/10 - Agree (3) Disagree

Basic Summery:
A decent mod, Well voice acted, fun/well mapped levels (and in some cases challenging) and fantastic music along side scenes.

Considering its free, this ones definitely worth giving a go.

In depth Summery:

Story - Short and sweet, any Half Life fan will understand whats going on in each level, Some would say its lacking story however I think they got just the right amount needed without shoving the plot in your face.

Game play - Not 'difficult' as such but there will be moments when you will have to think rather than constantly shoot. I personally had a couple occasions where I had to assess the situation more closely before moving on.

Voice Acting - Good voice acting, however the accents did throw me off a bit the first time I heard them, It didn't hinder the game however so I'd say it dosen't change anything.

Final Verdict - 10/10
I HL:Precursor 10/10 because it had clearly had effort put into and it was genuinely enjoyable, despite it being a short story it was still fun to play and thats what counts.
