S.T.A.L.K.E.R.

As I pointed out in the title, consider everything below this phrase as spoilers. Gonna space it out as much as possible to exclude them from the post preview.

So, ok. I finished the game and ended up siding with the Doc (this one's clear to me).

As anyone who also went with this one would know, this means I, at one point, fought our favourite (?) thespian madman, Scar, and got that mega-twist about how someone's just a copy of someone else.

And this is where I lost the plot, who got copied over whom? Was it Marshal* over Scar, or Scar over Marshal*? Because this Scar doesn't, well... have a scar. I literally felt my brain sizzling at that point and I completely lost the plot as far as this character's concerned.

Edit: * corrected from "Mitchell," which should also indicate just how in the weeds I am about this...
