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...
Precursor starts of with a series of quite familiar and not very entertaining puzzles, but soon becomes increasingly interesting and ends with a very challenging boss fight. The mapping is quite good, but the maps feel all too linear. The Storyline is virtually non existent making precursor a good, but definatley not excellent mod.
