As the title says...
This is a guide for people who want to make the achievements from Black Mesa.
And for those who need some help with them.
Hope I helped you guys with this.
NOTE: I DID NOT MAKE THIS TUTORIAL. I just wanted to help.
I think is better to search for it here than on YT.
Also, this is the best ever guide for the Black Mesa Achievements.
If you need help with them, tell me, I also made them all (25/25). So if you need some help just ask.
Have fun making them!
