You know, in space, your spaceship is more than just transportation and a place to sleep. It's actually a metal cocoon separating you from the airless void of eternity. Which makes one wonder why you'd ever want to trundle out an airlock and try to jump out and catch a starcruiser drifting at mindbending speeds.
Well, you're all daredevils, I guess.
Thing is though that once you land safely on the other side you still have to cycle the airlock and actually step inside the other ship.
Cher Coincidence was doing just that, but she forgot a very important step - always make sure the outer airlock door of the derelict spacecraft isn't jammed open. Oh, and always make sure the airlock safeties are functional.
Otherwise, you know, the inner doors open and the venting atmosphere blows you out on a one-way trip to Venus. Cher will be arriving in...on, we'll say a hundred, hundred and fifty years tops.
On the upside, Cher, you'll have a lot of time to contemplate your awesome, awesome astronaut gear as you wait for your suit's CO2 scrubbers to fail.
The rest of you have managed to board the wreck! It's all rusted out corridors and random wreckage floating by in microgravity. You'll want to choose your next steps very carefully, because this ship doesn't seem entirely stable.
There's a turbolift up ahead, pick a floor (1-4) and hope for the best!
