Many of Brad and Michal's friends are mentioned in the game. The security system voice was performed by Allison Hershey (the artist on the Inherit the Earth comic)!
Why I am I being paged? Not a clue.
You probably dropped your Alien Belt somewhere and forgot to pick it up. Can't have that lying around, can we?
Say, while I've got you, are there any plans to do anything related to LoT like the comic for ItE? And any more news on a possible LoT2?
Yeah, there's the whole "Announcement about the Sequel to The Labyrinth of Time (late 2006)" thing.

Well now I'm gonna have to play through parts of the game again to find more references. I only caught the one in the security message and the really blatantly obvious Terra Nova stuff.
