A thirty-minute leaked video has provided a world-first look at Legacy of Kain: Dead Sun, a AAA action game for Xbox 360 and PlayStation 3 believed to have been canceled in 2012.

Footage and images of the axed project were brought to light on the games forum NeoGAF, published by a user going by the username “Mama Robotnik.” Among the tranche of data and details, the post claims that Dead Sun was developed by the independent UK dev Climax Studios for about three years before it was shelved.

“The game was not projected to meet Square Enix sales projections, and was scrapped, to the enormous disappointment of staff who had dedicated a lot of work to the project,” the NeoGAF poster claims.

“One source recalled that staff came in at weekends to continue working on the game, while higher-ups already knew it was canceled.”

It is said that the game featured an online deathmatch mode that was disconnected from the main campaign. “This was the only part of the project to survive the cancellation, and has now been heavily expanded upon and released as Nosgoth,” the post read.

The area shown in the video is said to be called The Wetlands; a hub world featuring expansive dungeons housing huge bosses. “Think if HBO did Zelda,” one alleged source said.

Meanwhile, the NeoGAF post also claims that the project was initially envisioned as being somewhat small, expanding into a AAA-sized Xbox 360 and PS3 game.

“In its final form, the game was strongly considered to be PlayStation 4 launch title,” the post adds. GameSpot has contacted Square Enix for comment.
