The auto-aim firing system is a new gameplay feature in Metroid: Other M. When the game is in third-person mode, Samus will automatically target enemies when firing Beam shots at them. The lack of manual targeting is due to the limited control possibilities with the sideways Wii Remote. In Search View, manual aiming becomes possible with the screen-pointed Wii Remote as well as Lock-on, which enables the firing of Missiles. Auto-aiming is not possible in the 2-D games or Prime Series, although Samus is able to lock onto enemies in the latter.
