Trials Fusion - Guida Inferno IV [PS4-Xbox One-360-PS3-PC]
Sooner or later you'll have to face it too, unless you want to quit first, ladies ...
Guide Trophy / Objective "In the flames of hell"
It is the most difficult and probably the longest track in the game, so much so that it also deserves a dedicated result. The track Hell 4 unlocked by earning 110 medals and completing "The Great Crater". After unlocking Inferno IV you will need to complete it in less than 30 minutes and with less than 500 accidents (tsskk !!!) to unlock the result.
Needless to say, it is worth trying only after having done a lot, a lot of practice with the other tracks, in order to be masters of the most advanced trial techniques. The recommended bike for this track is the Viper Pit, but of course you can use whichever one you are best with.
Below is a video showing how to overcome the most difficult points in the time limit to get the gold medal. Good luck.
