Operation: Black Mesa is a total Source remake of Half Life: Opposing Force. Using the Source engine, the developers plan to recreate the Black Mesa research Facility as it was seen by Corporal Adrian Shephard of the H.E.C.U. Half-life: Opposing Force is still an amazing game, although it is not nearly as amazing as it was when it was released.
Environment and character concept art.
