You're holed up in a secure military bunker in the year 2097, and while a war-ravaged world rots above, you hunker down, face lit by the green glow of a terminal, and troll IRC-style chatrooms for survivors. Unfortunately, the "bots" who ravaged the planet have picked up on the technique, so it takes careful conversation to distinguish between a genuine human being and an impostor.
That's right: it's Turing Test, the game! Your supervisor @Roger directs you to continue grilling Luke, a sudden and unexpected chatroom inhabitant, and the story unwinds as you gradually hit on the keywords triggering the sharing of his troubled past -- or the past he's faking, trying to hide the fact (through conspicuous typso... I mean ytpos... I mean typos!) that he's a killer robot, waiting to glean enough information out of you to pay a little visit and render you down into your component particles! The conversation that results isn't up to Racter or ELIZA levels of lucidity, but the setting and grim atmosphere moodily trump their bland contextlessness.
