Originally meant to focus on Zack, Last Order highlighted Tseng's feelings and position in the Shinra company.

Last Order explores situations shown and referenced within Final Fantasy VII and other Compilation titles.

[1] The world of Final Fantasy VII, referred to as "the Planet", is dependent for its survival on a flow of spirit energy called the Lifestream.

[2][3] The megacorporation Shinra eventually rises to power and begins extracting the Lifestream through mako reactors, killing the Planet.

Other roles include Keiji Okuda, Atsushi Imaruoka, Ryūji Mizuno, and Daisuke Kirii as members of Shinra's military unit who attempt to apprehend Cloud and Zack.

[15] Last Order: Final Fantasy VII was produced and scripted by Square Enix collaboration with Madhouse[16] and directed by Morio Asaka.

[16] Tetsuya Nomura, the character designer for the Final Fantasy VII series and co-director of Advent Children,[20][21][22] acted as the supervising director.

The production crew considered the most challenging part of creating the OVA to be making "Nomura's drawings move on screen".

[16] Nomura and Ofuji agreed that many scenes showing important events and feelings in Final Fantasy VII had been fragmented and disjointed, and so they had decided that those scenes would be the subject of Last Order, giving the audience of Advent Children (the film Last Order was released with) a "more enjoyable understanding".

[23] The OVA was included in the North American "Limited Edition Collector's Set" of Advent Children, released by Sony Pictures Home Entertainment on February 20, 2007.

[31] Only 77,777 copies of Advent Pieces: Limited were produced in Japan, and they are no longer available, having been sold out months in advance of its release.

Chris Carle of IGN noted that Last Order was "the true meat of the new extras [in the Advent Children collector's set]… a traditionally animated chapter for Final Fantasy fans that centers on the story of Zack and Cloud" and that "it adds even more dimension to the story [of Final Fantasy VII]".

[34] However, Hideki Imaizumi, the producer of Crisis Core, stated that they had received "considerable negative feedback" from fans, who were displeased with changes made to the Nibelheim event in Last Order.

Due to this, the scene was redone for Crisis Core, and the production crew was careful to avoid making the same decisions.
