Top Gun: Fire At Will was released by Spectrum Holobyte in 1996 for the PC and Sony Playstation, but it was originally a cancelled title for the Nintendo 64. The title features any actors from the film, with James Tolkan reprising his role as Stinger. The game’s overall plot focuses on the player-character, Maverick, going to combat in Cuba, North Korea, and Libya against a secret group of mercenary pilots called the “Cadre.”
The N64 version was probably canned because it was seen as an economic risk, and they decided to move the project on other platforms that were more cheap to develop on. Probably the game released for PSX and PC was not the exact same one as the original N64 concept and for more informations you can download the original pitch for Top Gun 64 in here: Top Gun Ultra 64 Pitch (PDF)
Update: as wrote to us by Ross Sillifant, here are some more info on the cancellation of Top Gun 64:
Microprose CANNED N64 version of Top Gun, despite being one of the 1st Non-Japanese firms to be granted a publishing licence for the N64, because they’d lost faith in Nintendo. Tim Christian, European Md of Microprose told EDGE magazine that Nintendo were coming in last and the public is going to see them as the 3rd Next generation platformin every sense and by the time the N64 arrived in Europe, the average software price for PS1+saturn could have dropped considerably and you’d be able to buy top quality games on Playstation and Saturn for under £30. How could a mass-market develop around a machine with games selling for £70? Tim thought the N64 would be ‘sunk before it gets out the harbour’ as far as Europe was concerned.
