Regardless of the fact it's being put together by Kotaku Australia community stalwart FatShady, I've become a massive fan of the University of Trials. The University of Trials is a video series that helps players learn all the different techniques that will enable them to breeze through the brutally difficult Trials HD and Trials Evolution games.
I've been following the University of Trials series since it began and I think this is the best one yet. Mainly because it takes a series of individual lessons shown in previous videos and helps you put them together in the context of truly difficult 'extreme' tracks. It's one thing to be able to perform the different tricks and skills required, it's another thing to recognise when and where to use them.
Dark City Run is used in the example -- and it's one of the most difficult tracks in the game. There's some great advice in these vids and if you have any intention of playing the game, I thoroughly recommend watching.
