Concentration

The Concentration Move is a new technique mentioned in the interviews with Nate Bihldorf and Yoshio Sakamoto for Metroid: Other M. Both confirmed that enemies will no longer drop Energy Capsules when defeated. Instead, if Samus Aran's health is low, she can go into first-person perspective and hold the A Button down to restore some energy and all of her Missiles. Not all energy will be restored, only enough "to survive until the next Save Station". This technique may be similar to or even be the Crystal Flash.
