Installation instructions are a little vague, my way of doing it was to follow the ModDB instructions and launch from inside the Black Mesa file, any other way of doing it and it just refuses to load.

Don't know what to make of this, it's not very well designed, the map's are confusing AF, was running around for a good 10 minutes per area trying to figure out where to go, how to get there and when I got there what I was supposed to do, the rooms lock you in but I'm not too sure why, if it is to see something then there needs to be a clue as to what, only to release you after a while, there are sooooo many enemies that turn you into a pin cushion within seconds, could be I was playing on hard but I swear those bullets hit harder than Black Mesa standard issue, it says that there are different paths and ways to complete but all the paths converge so there isn't really a different way of playing, the "stealth" is very lacklustre, I found it easier just to run around the NPC's while they fought each other, don't know if that's how its supposed to be played, the NPC's all have the same voice actor, which I assume is the mod maker's voice but the audio is tinny and low I could barely hear them, turning up the NPC volume does kinda' work but then all the HECU voices are super loud, the brightness has issues, turning it up causes the torches, glowsticks and beacons to turn into flashbangs, the console is filled with errors, I'm seeing a lot of red, the FPS dies with the firefights between the vorts and the HECU, this can be fixed by not looking at the firefight, there isn't a intro like Black Mesa or Blue Shift which detracts from the game, I know the mod maker wanted to get into the action but the I would've liked to know the lore of the character we are playing as, it would've added another 20 minutes to the game at least, the lore doesn't make much sense either, this guy is a scientist, he doesn't have a HEV and he isn't wearing combat armour, why does my armour increase when getting HEV batteries and why does he know how to use a MP5, the design of the levels doesn't match the lore either, it feels like a mismatch of the waste processing in Blue Shift combined with Power Up from Black Mesa, we're in Sector D, in Half Life lore that is the office complex, why is it so convoluted, there are many places to get stuck, I had to console noclip my way out of areas that I'm guessing I wasn't supposed to be in but with how the levels are designed how am I to know.

It's really short, like, 25 minutes, even with the glitches, crashes and FPS issues, the level select says 2 chapters but it feels like less than 1, again, if it had an opening it would be longer, it's a good mod but it needs a lot of work, the levels need redesigning, more straightforward design, I don't mind being redirected but when the route itself is no clear then the level needs work.
