Where to find the hat / pizza needed to unlock the Rare Specimen, the Rarest Specimen and Pepperoni Precipitation, and usefull spots to leave them at. Both secret endings included in the video.
This concludes the new achievements I wanted to cover, had a great time making these videos. I'd love to do more, so if you still have some other achievements you struggle with and would like to see a guide for, please let me know! Doesn't have to be Black Mesa achievements, please do comment on what game / achievements should I work on next.
