Dusty’s Revenge developer PD Design Studio created an unofficial Final Fantasy VII beat ‘em up. Final Fantasy VII Re-Imagined is a one stage level set in Midgar with Cloud and Tifa as playable characters. Barret acts kind of like a summon, he can shoot enemies from afar. The game also incorporates a materia system which modifies a character’s last hit in their combo.
