64 Wars (lost build of unreleased Nintendo 64 game; 1999)
64 Wars, also known as Advance Wars 64, is an entry in the Wars franchise. Plans called for interconnectivity between GameBoy Wars 2. 64 Wars was showcased at Spaceworld 1999 with a release date of January 29th of 1999. Despite this, the game was cancelled for unknown reasons.
Advance Wars 64 would have followed the same format as other games in the Wars series which is a tactical role-playing game. Players would oversee a 2d map, but when battles would occur, the battles would render in 3d. Additionally, the game would have utilized the Gameboy Transfer Pack with GameBoy Wars 2 to gain access to several features, such as the ability to transfer match progress between the systems. The menu for this function still appears in GameBoy Wars 2, but can't be used.
While the game was never released, screenshots and video of 64 Wars have surfaced. Despite this, 64 Wars has never been released.
