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.
Operation Black Mesa.
Amazing work. A little to much purple for my taste but other than that it's perfect.
Looks like Adrian Shepard fighting so hard there!
Looks crazy
Bursting with color and detail!
PINK ATTACK
Boi that hud.
Looks so much more atmospheric now
