Yep, I am missing ONE health upgrade and I have NO idea where it is. There is also no videos on YouTube showing where they are...anyone got a list or something ?
Off the top of my head, the ones I REMEMBER collecting:
- The one behing the ventilation gate right before the freight elevator - The one behing metal fans right before the Sundowner fight - The one on the rooftops in a blue chest that spawns a fight with a ****load of Sliders
I also probably got all the obvious ones out in the open or that requires minimum exploration... except one I guess haha.
