In this post about a derelict-crawling GLOG I said "This is just classes, and it probably won't go further than that". Well, it turns out I'm a liar.
Orbiters Local 519 is a GLOG hack using those classes, built for an open table or set of disconnected one-shots. In it, the PCs play a group of scavengers sent to recover delicate resources from wrecked starships. It has two important differences from your standard dungeoncrawl, however: one of them is simply the 0g environment, but the other is more interesting: destructibility.
Generally, a dungeon will stay physically the same when the PCs enter to when they leave - maybe they'll kick down a door or two, but they won't be caving in rooms. In Orbiters Local 519, not only will they be tearing through walls, but the derelict will be falling apart on its own. Pipes explode, gravity falters, derelicts spin, and entire rooms can tear off from the structure.

Example Derelict One - EAS Aspen
A Navy railgun corvette was destroyed in a skirmish about 7 months ago. No survivors are expected, and sensors are picking up a radiation leak. Hopefully you can get in and out before the Navy realizes we're here.
Example Derelict Two - ISK Halamandaris
A biology research ship, destroyed by a power failure incident. The AI, Pythagoras, should still be online. Most of the habitat domes are still in one piece, and we have no idea what could be inside. We shouldn't be facing any competition for this one, feel free to take your time. As much as you can, anyway.
