Roll Shot

Prime 2 is the only game in the series where you can shoot 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 rollshoot (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.
