Koei Tecmo has released three new gameplay trailers depicting the fighting styles and move sets of Eren Yaeger, Armin Arlert, and Levi Ackerman.  Armin's the only character within the three videos that seems to only be a cooperative character rather than a playable one but it's clear that you can choose whichever character to be your support in your fight against the titans.  The videos end with either both the pre-order bonuses, (special character costumes for Eren and Levi), as well as what will come inside the box when you pick up Attack on Titan for either PS4, PS3, or PS Vita.

Check out the three trailers below:
