The story-focused trailer shows off Samus' voice.
Nintendo released a new Metroid: Other M trailer that is comprised of cut-scenes that show off the heroine Samus Aran talking about how she feels, and how she is young and naive.
This also gives fans a chance to hear Samus' much talked about voice acting, which has been the main source of criticism for the upcoming game, which is set for a June 27 release in North America.
