Satan’s Hollow is a shoot ’em up arcade game designed by Bill Adams, and released by Bally Midway in 1982.
The gameplay is similar to Galaga from Namco: the player must destroy the flying formations of gargoyles in order to pick up pieces of a bridge that must be built over a river of lava. As the game progresses, the gargoyles begin to throw exploding eggs, along with rocks that can destroy bridge sections; the player also occasionally faces disembodied devil heads that float around the screen and spit fire. In addition to firing rockets at the enemies, the player can use a shield that will destroy any enemy touching it. However, this shield can only be used for a short time before it must shut down to recharge. Gargoyles will sometimes attempt to steal a ship from the player’s reserve lives, similar to Galaga.
