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 is one of those rare mods that captures the essence of Valve's games. However, it is somewhat inconsistent. The brushwork is all solid but the locations feel uninspired. The combat is difficult but sometimes feels tedious. I am also disappointed that the custom weapon was removed.
Still, this is probably going to be on Top Ten lists for a while.
