“Genuinely did not think it would take me 38 hours to beat. Lore is good, world is good. Level design suffers a bit from the designer not hand holding you and some puzzles were a little frustrating, but fine. Source…”

“G-String is a highly atmospheric Half-Life 2 full-conversion that brings across a dystopic end-of-the world cyberpunk-scifi atmosphere very well, but is a bit basic in terms of systems and gunplay (well, HL2-mod).…”

“This is the worst Source mod I have played. I didn't think such a thing was possible given the care and love people put into such an engine given the culture around this technology. Off the bat, the level design works…”

— a player, Steam review · 6 hrs played“they're absolutely right about this game. you will get pissed off that you have to parkour off the tip of a piece of rebar so you can climb through yet another vent. also the combat sucks and you will loathe it at some point during the gameplay. story makes no sense. but…”
— a player, Steam review · 11 hrs played“Incredible world-building, easily the best realized "dark cyberpunk" setting I've ever seen.
