Skull Cracker is a 1996 supernatural beat 'em up video game^[1] developed by American studio CyberFlix and published by GTE Entertainment on Macintosh and Windows. It is sometimes considered a spiritual successor to the 1991 title Creepy Castle, which the game's head of technology William Appleton had previously written for Reactor Inc. Skull Cracker was conceptually designed by Ben Calica.^[2]

After the release of Titanic: Adventure Out of Time, Cyberflix released this old project which had been sitting in the vaults for a few years.^[3] The game was demoed on October 28, 1995 at the Double Tree Hotel (Crowne Plaza) in Rockville.^[4] It also previewed at the 1994 Summer Consumer Electronics Show along with other Cyberflix games, presented by Paramount.^[5]

The developers described it as an "old-fashioned side-scrolling arcade game".^[3] The game sees the player battle through 16 levels of the undead and monsters.^[6] The game contains 50s-style monsters and 90s-style urban grit.^[7]

GameSpot offered a scathing review, panning the title's "bad art, poor animation, limited controls, no decent action, lame gameplay".^[8] MacLedge felt the game was a letdown from Cyberflix's previous work.^[9] Inside Mac Games praised the title's intriguing storyline, witty humor and exciting gameplay.^[10] Cyberflix head Scott Scheinbaum would later say "Every company makes mistakes, and that was ours...It should have come out a year and a half before it did", noting that 1994 technology seemed stale by 1996.^[3] World Village noted the game was a departure from the history-based title Titanic.^[11]
