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. 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. 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 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. 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.
