Once you’ve defeated four of the eight Robot Masters, Dr. Light makes some upgrades to Rush, allowing Mega Man to summon the Rush Jet.
Like in previous Mega Man games, Mega Man can jump on the Rush Jet and it will move forward until either you jump off, manually deactivate it, or it runs out of energy. It can also be slightly aimed up or down as it jets forward.
With proper timing, Mega Man can land on the Rush Jet in midair, allowing him to reach all-new locations (such as the Weapon Tank in Bounce Man’s stage) and substitute it for the Pile Driver if needed.
