Hi there, I'm Marc(1k1). I've started many a game project in my time but never actually finished one, much the same can be said about my time spent animating however I have done better in other creative fields such as art and video editing, the latter you can see on my Youtube Channel. I also have an interest in playing guitar and maybe at some point in creating some music, but we'll have to see about that.
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.
