Melt is the beta version of Ed Hunter is a rail shooter video game that was released in 1999 for the Playstation, based on and accompanied by Iron Maiden’s music. The game objective consists of rescuing the mascot of Iron Maiden, Eddie, from a prison while passing through game settings evocative of the albums. [Info from Wikipedia]
Thanks to Srđan we found out that Melt was the same project as Ed Hunter:
There was a sticker on the Maiden compilation Best of the Beast where it said ”Introducing Melt- Eddie’s own state-of-the-art 3D game!” and there was the picture which said Playstation and MELT. Using WayBackMachine I was looking at the old Iron Maiden site, circa ’98-’99 and it says that the game Melt has changed name to Ed Hunter. So there you go. Also , according to the description, the game was changed too, from the gameplay to the style.
Thanks to Pachuka and Srđan for the contribution!
