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...
This mod is absolutely fantastic. It's wonderfully put together, with Valve-like quality. Truly one of the best Half-Life 2 story tie-ins since Dangerous World.
I hope to see more from this team.
