I haven't got Yuri's revenge installed at the moment so i can't comment on that. As for the teleporting bunker, it is more like a teleporting tunnel network. I got the idea from science fiection films and books (Dr Who amongst others).
The idea behind teleporting in Star Trek etc is that the teleporter machine scans your molecular structure and sends the information to a machine elsewhere which then reconstructs an exact copy of you. The first machine then destroys you so the new copy becomes you in a new place.
Some bugs can happen, literally, if bugs get into the machine, like in the movie The Fly, when a fly is teleported together with a human and the machine on the destination side mixes the two together to make a half-fly half-human result. Another possible bug is if the machine at the source fails to delete the original, then you would get duplicates.
However the teleporting thing in my mod is less like Star Trek and more like the Tardis in Dr Who, from which it takes it's name.
TARDIS - Wikipedia, the free encyclopedia
Whereas Dr Who's TARDIS looks like a 1950's London Police Box, the one in my mod looks like a portable toilet. It is bigger on the inside than on the outside which is how even tanks and big vehicles can fit into it.
