In Armored Core - Last Raven, Toothpick - Fracture that is fought in the VR Arena, uses the cover AC of this game. The only difference between the two is that the Last Raven variant doesn't have the CROW extensions as they, like many other parts, were removed from Nexus onward.
The back of the cover art incorrectly uses a screenshot from Armored Core 3, specifically Attack Mirage Forces.
