Primal Rage was released in September 1994.
The concept of the game borrows heavily from Taito's 1992 arcade unit "Dino Rex
Atari had intended to create another upgrade for PR 2.3 and was scheduled at this time for January 1995. This upgrade would allow the player to face a boss monster at the end of the game for total domination of the world. The final boss was supposed to be a horned dracolich (animate dragon skeleton) imprisoned in the moon, with three claws on each limb and 3 spines on the end of his tail. It was also supposed to have the powers of flight and the ability to drain the opponent's lifeforce. The final battle ground would be a moon scene with the skeletons of numerous dinosaurs laying around in decaying states. The ground would be covered with craters and giant, glowing cracks. A teleportation warp would exist overhead. Unfortunately, Atari scrapped the idea for this upgrade because Time Warner Interactive been too busy at this time to work on an upgrade and the boss was never came into existence... :(
The June 1996 issue of GamePro magazine confirms that Ellie Rovella of Gilbert, Arizona became enraged when her 11-year-old son bought Primal Rage for his Sega Genesis and played the game using GamePro's strategy guide to execute Chaos' golden shower fatality. Rovella was so outraged she not only returned the game, but also launched a grass-roots campaign. As part of this, the fatality was famously censored on the Super Nintendo version by placing a large 'censored' bar over the screen when it was performed.
