Just a note that some of the wiki information might be inaccurate.
Part of the reason for this is that a piece of information might just be lacking or inconsistent -- like the name for something -- in which case I use a placeholder. As an example: one device has been called, variously, a "Wall of Light", "Electric Gate" and "Light Gate", by different people. Which is the correct term? I've seen the "Wall of Light" reference more often (and it sounds good

), so that's the one I pick.
The rest of the reason for this is that piecing information together from disparate articles is tricky.

For instance, my girlfriend informs me that "turrets", "pylons" and "watchtowers" have been mentioned, and some articles talk about automated "watchtowers" and "turrets". Now, are these three different things, or two different things, and which of them does what; or are they the same thing given different names by different people?
Of course, the wiki will be refined and corrected as we get new information. Which hopefully is soon...
