Acuity mod for Black Mesa

So, this is a mod that is still in planning stage. After the nuke, Black Mesa was almost destroyed, however, some of the areas managed to withstand. A scientist survived the nuke thanks to the H.E.V suit but suffers from major vision loss and deficiency. Battling with Xen creatures and visions, the scientist must find additional H.E.V modules to fix these symptoms. This is the general idea of the mod. I am working on this alone and this post is to keep me in track. Thank you for your attention.
