Oooh, I have one OP2 related!
Arklon, Mcshay, and I were playing Mcshay's new (buggy) map (it has
working multiplayer AI!) and the victory conditions were disabled. It's Survivor, so your goal is to launch the Evacuation Module. Anyways, I launch the Evac Module just for fun and JUST as it says "Colonist Evacuation Module deployed" a MASSIVE earthquake desimates my base. The only thing left standing was the spaceport. (Took out most of Mcshay's base too.)
Interesting note: After I launched I had 2 workers left, and it took about 1000 marks (yes, that's supposed to be one thousand) for one of them to die. We quit before the second one died. I guess the quake released some kind of unknown element hidden in New Terra's crust that causes prolonged life expectancy in humans. And removes their requirements for oxygen.
