Out of the Deathmount is an on-rails 3D shooting game for the Virtual Boy, that was to be released in Japan in March 1996 by J-Wing, but was ultimately cancelled due to the discontinuation of the Virtual Boy.
Set in the near future, the goal of the game is to escape the mountain of death. The player rides aboard a rail car while controlling 2 handguns at the same time to bring down approaching enemies.
