GoldenEye 007 designer Martin Hollis has revealed details of his original intended followup to the beloved shooter.

Codenamed Game Zero, the game was dreamt up in 2000, after Hollis left GoldenEye developer Rare in the middle of Perfect Dark's development.

Proposed as an exclusive for the Nintendo GameCube, Game Zero would have been an action platformer set in voxel-based sandbox levels, in which players could mine elements and build structures.

It would have featured vehicles, laser guns, an alien planet, and destructible environments.

Ultimately, the game was deemed too ambitious for either the then-current console hardware or the day's gaming audiences to handle , and was cancelled after three years in development.

Until now, Game Zero was so cancelled it never even got shown to the press or public, but Hollis says the game's cancellation wasn't as depressing as it might seem.

"If some of your projects don’t fail, that’s evidence you’re not taking chances. We are taking chances and a lot of our projects end up being cancelled or put on the shelf. [...] Not every daring idea can be bought to fruition."
