50 more words every sci-fi fan (and most gamers) should know

We're on a mission to create a complete science-fiction glossary, and here are 50 more words every sci-fi fan should know. (Yes, FPS and RPG fanboys, there are lots of gaming terms mixed in here.)

It all began with 75 words every sci-fi fan should know, which gave way to another 25, then 30 more, and finally 40 more after that. We won't stop until we've got a complete science-fiction glossary, so here are the next 50 words every sci-fi fan should know. (Yes, FPS and RPG fanboys, there are lots of gaming terms mixed in here. As the first generation born into a world with ubiquitous video games grows into adult authors, the twin lexicons of sci-fi and gaming are overlapping, intertwining, and cross-breeding with much artifice and aplomb. See Gibson, William and Stross, Charles.)
