Last Order: Final Fantasy VII is an OVA.
The OVA is an anime rendition of two flashbacks that took place in the game. One details events from five years before Final Fantasy VII, revolving around the Nibelheim scenario that focused on Zack Fair, Cloud Strife, Tifa Lockhart, and Sephiroth. The other involves Zack and Cloud on the run from Shinra. The anime cuts back and forth between these two flashbacks, linked by the Turk commander Tseng's reflection on the Nibelheim events.
Last Order also forms the basis of the PSP game Crisis Core: Final Fantasy VII, and serves as a tie-in with the mobile phone game Before Crisis: Final Fantasy VII, as several of the game's playable Turk characters appear as minor characters, with some getting spoken lines.
