Nero or Dante can perform a launch jump off of ledges that sends them flying far forward much further than a normal jump. This can be used to collect secrets or as a shortcut. To perform it, stand facing a nearby ledge that you can jump off from. Perform the Streak or Stinger attack (while locked up, press [Up] + [Attack]) and Nero or Dante will dash forward. The ledge cuts off the attack animation and will instead launch your character far forward.
