It's been so long since I did that level, I'm having trouble recalling an exploding elevator. Sounds nasty.

: I try and run down the
: side of the control room on Two Betrayals to skip enemies and push a Ghost
: through the broken doors to run past the final encounter

I remember spending some time on that trick, and finding it a bit… er… tricky. I don't seem to've covered it on my site yet. Dang. That's another item for my huge backlog.

: I go to security first on Silent Cartographer.

Sudden random thought. Did Scurty name himself that way in honour of the security substation? I mean, just remove a few vowels…

: I probably haven't played through AOTCR and Two Betrayals
: "properly" in years at this point

Well, I haven't played TB for a few years I reckon, but I do AOTCR quite a bit. I was actually giving it a go yesterday, as a bit of relaxation from the business of making movies. I was doing it on Legendary with covie weapons only. Got killed, bah! Must be out of practice.
