TF2 Update Sound Samples Revealieodiated

I woke up, like many of us, to Steam telling me that TF2 had updated. I had no idea why. And then I turned on my browser, where PCG's twitter pointed me at a youtube video of all the soundfiles in it. Which appears to be some game mode about forming and betraying friendships. It's life at RPS as a TF2 mod, basically. Listen to them below and then speculate wildly...

This is giving me SHODAN flashbacks, admittedly.
