My record as the Computer: 24 dead clones in under an hour. We were playing 1st edition adventure Clones in Space. All the clones are activated and sent to outerspace. One player herded his clones into the airlock and then hit the blinking read button (opening the outer door). The others tried to wield a piece of metal over a small crack with a plasma gun (blowing out the side of the ship). Sad thing on that was that I told them that the crack was not losing enough air to be a concern.
One of my very few TPKs, and I got no blame whatsoever from the players.
