Just to at least answer one mystery, that's one of the tees our marketing guys gave out to people in our Alien Isolation push.. it's a Seegson Synthetics one 
Just wanted to say that Alien: Isolation is the only horror game I've ever bothered to purchase myself beyond watching a let's play and it's awesome. The tension, world building/setting, and the characters (Amanda and Samuels, at least) were great. 
Also, I kind of want one of those shirts now. lol
But back to the old drawing board, BSN.
I just picture Alistair having a good chuckle over this feeding frenzy of thirst. Or being vaguely creeped out that people are now stalking his and his wife's Twitter/Facebook. 
I saw someone a few posts back deducing out whether he's left or right handed based off picture observations. Clever, but I'd be slightly creeped out if I was him. XD
