You're play a security guard be employed as Black Mesa Research Facility. In serving highly level research facility of the special one officer black security, they also called as secret security personnel, so your work need to going the safeguard through highly level scientists. You're familiar with the who knew name Eddy, but he try a hiding secret behavior, that you would be going next one justice sentencing in the depths of him, at the end must to stop his conspiracy.
Return to Black Mesa Research Facility once more, this time, as security guard Brad and experience alternate story of Half-Life. Starting your day as usual you find yourself in the center of chaos and who else if not you is there to save the day? The mod features 40 different maps and at least 2 hours of gameplay. The level design is amazing, almost making you forget that this is just a mod and not an official expansion pack like Blue Shift or Opposing Force. As the matter of fact, Black Guard is a mix of both! Custom models and new soundtrack also fits nicely! Sadly, not everything is so great. To begin with, the English is nowhere near good, even if you do install the path it is still hard to understand, on the other hand, what else would you expect, it was made by Chinese! Another thing, while the mod features quite a big levels, most of the time they are only for item fetching. You may encounter a few crashes here and there, at least I did, but once you get trough them, the game is really great!
