Half-Life was brilliant. It revolutionized the first person shooter, provided hours of entertainment, introduced us to a world of weapons and bizarre creatures, and most importantly- it (unlike most video games) stayed with its plot throughout the game. Then Opposing Force came along- a mission pack that was a game in and of itself, the player now switching sides and playing through the Military- the enemy in the original Half-Life. Although less plot-driven than the original (its cheif weakness) it still managed to create a very good gaming atmosphere, even if it didn't quite match up with the first. Then Blue Shift came along. I (although a huge fan of the first two) was apprehensive; I felt Sierra was trying to capitalize upon the success of the first two and, running out of ideas, was stretching things thin by having the player play as a security guard...Barney Calhoun. I was mistaken- The game is faithful to the first (with none of the weapons from OP4, but most from the original) and adds in some new things....people, locations, plotlines. It was most enjoyable to navigate Barney Calhoun through the waterworks and train depots of the Black Mesa compound, and the ending was significantly different than that of the first two.......I was very impressed by its simplicity and practicality. Although rather short, with no new weapons or aliens, I highly recommend this Mission pack- do the Half-Life devotee or someone new to this family of games
