So far I've managed to fling my self into the vacuum due to lag. Where I either froze to death or suffocated. I'm not sure.
That is exactly what I did the first time I ever played.
Me: Hey, an airlock. Can I open it?
Me: The inner door opens! Is there an interlock to prevent the outer door opening at the same time?
Game: No.
Air: Whoosh.
Me: Gasps (but if I had a mask and airtank would have said "I can't get back inside!!")
Of course, now I know that if you're accidentally in space, you can throw stuff to move yourself in the opposite direction. Take off your shoes or something, throw them in the direction you're going in, and you'll reverse direction and go back through the door again.
Mostly what I've been doing is finding AFK players, stuffing them into bins when no-one's looking, and flushing them to the disposal room. Having turned on the belt and grinder and opened the doors to space. And welded shut the access doors.
And the players who think it's funny to poop all over the station. I think it's funnier to hit them in the head with an oxygen tank and flush them to the grinder...
Funniest moment so far was when I heard a radio message from an astronaut, someone who'd got access to a spacesuit and jetpack and gone off exploring. He was asking why there was a guy welded into a locker with a bottle of rum, drifting endlessly across space somewhere. Thirty minutes before, I had passed that same guy in a corridor. As I passed him, someone else ran past in the opposite direction, and I was attacked in the eye with a pen. I thought it was the first guy, so I pushed him into a nearby open locker, welded it shut, dragged it to the disposal room launched it into space.
Two minutes later, was standing in the corridor when the same running guy ran past and stabbed me again. I'd got the wrong guy! I never managed to catch the real attacker and send him to retrieve the first guy...
I have to suppress the impulse to write 'say' in front of every statement now.
