All characters have some sort of aerial move(s) that alters their trajectory in some way, though they don't all behave as a "triple jump". These include:
Kratos Up + Circle (Icarus Ascension)
Drake Up + Circle (Zipline)
Jak and Daxter Forward + Square (Jet Board Dash Punch)
Nariko Up + Triangle (Heroine Movement)
Raiden Forward + Circle (Charging Cut)
Attacks like these can be used not only for offensive purposes, but to better position yourself in battle. I'm interested in seeing how players incorporate these mobility attacks to their overall movement, especially on bigger stages.
