Ring of the Combines
 

Was this added later on? dont remember, either way was just wondering if it is in fact in the game yet or not

It's not in, and wasn't in on live either. self only combine portals was added late in kunark. pretty sure there have been severals posts before about it, but I'm too lazy to do a search :)

Was not in live :). Yep, there are plenty of posts talking about this topic
