My friend and I just 2 manned Urrox, it wasn't intentional but our third left at Urrox and left us screwed. We did not want to restart all the way from the beginning so we had no choice but to try, and man was it hard. In the end it was very satisfying and we can now say we have 2 manned Urrox lvl 34. Video is on my profile for proof :) If you have any questions ask away. Edit: we were both only lvl 33
