Looks useful and well organized! I haven’t downloaded the mod (yet), is it good?
The guy that made it was subsequently hired by valve.
So I guess you could say it’s good.
In my opinion is one of best designed mod with nice story and gameplay.
You aren’t Gordon Freeman. You are haxed Combine Soldier in stolen H.E.V.
There is alot of joy even without Gravitygun.
It’s really hard and fun to play on Hard difficulty (walkhtrough is on medium 
)
Link for mod-download is under ‘annotations on!’ warning on YT 
i played and finished it recently
it is quite difficult compared to hl2+episodes
nice story, amazing puzzles !
worth a try!
