I'm searching for an old Map I've once played it looked like this:
A completely sci-fi whitish room with in the middle a sphere core "like the combine core" that was charging like ever 15 minutes or so, the core went active and the whole room slowed down time and changed color to orange/red.
There where a couple of platforms build around the core with elevators etc...
The whole theme was very futuristic and portal like!
If you know witch map I'm talking about please let me know!
