The Rush Jet Adaptor is acquired differently in Mega Man 9 than fans may be accustomed. Instead of getting it when defeating a specific Robot Master and assimilating the skill along with that Robot Master's weapon, the Rush Jet Adaptor is earned by Mega Man after any five Robot Masters are slain. When the fifth is killed, Roll and Auto will automatically give Mega Man this adaptor.

Below is the suggested order to defeat the Robot Masters in, as well as which weapons to use on both them and the bosses in Dr. Wily's castle. Keep in mind that in terms of the Robot Masters, you can jump in at any point, but we recommend starting with Galaxy Man and going from there.
