Roll Shot

A roll shot or roll shooting is a technique that is only possible in Metroid Prime 2. It involves shooting a Beam or Missile in the process of unmorphing. This trick can save minor amounts of time throughout a run, usually when rolling into portals or towards a door. The only requirement is to be morphed and then press A and X on the same frame (or Y and X if opting for a missile). Also, you must be on the ground as you can not do this airborne. Finally, an interesting side-effect is that you will begin charging whatever beam is equipped after you roll shot (or will begin to initiate Seeker Missiles after a Missile, if you have Seeker Launcher). This can sometimes be useful with Power Beam if you want to start charging a Super Missile early, or if you want to fire Seeker Missiles quickly as well.
