Primal Rage

Primal Rage is a 2D fighting game in which two players select characters to battle each other in one-on-one combat, or a single player is faced with a campaign of fights against CPU opponents of increasing difficulty. The final battle of the single-player mode (accessible only at difficulty level 10 or higher) consists of fighting all the other monsters, this time with an increased power bar, made available in a minigame prior to the fight. A total of seven fighters are playable: Blizzard, the ape-like god of good; Armadon, the ceratopian/thyreophoran-like god of life; Talon, the raptor-like god of survival; Sauron, the tyrannosaur-like god of hunger; Chaos, the ape-like god of decay; Vertigo, the cobra-like goddess of insanity; and Diablo, the tyrannosaur-like god of evil. Each character has its own specialized set of three attack moves and abilities.

The object is to deplete the opposing character's health meter before the player's own runs out. There are also seven different background stages where fighting takes place, each one representing one of the character's innate domains: the Cliff (Blizzard), the Hollows (Armadon), the Strip (Talon), the Cove (Sauron), the Ruins (Chaos), the Tomb (Vertigo) and the Inferno (Diablo).

A massive meteor strike has devastated Earth. Human civilization comes to an end in the ensuing cataclysms and humanity regresses into tribes of Stone Age dwellers. A primordial rainforest covers the land and the continental landmass has shifted into the shape of a fire-breathing dinosaur skull. The planet is now primitively referred to as "Urth" by the survivors of the cataclysms.

Seven fearsome creatures with supernatural abilities emerge from their slumber deep within the Urth's crust, and become worshiped as gods by the humans, who form segregated clans beneath the ones they follow. The beasts themselves are divided between those who wish to keep peace on Urth, and those who attempt to plunge the world into further chaos for their own benefit.

Animator Jason Leong recounted: "Every year [Time Warner Interactive] throws a brain-storming session where everybody brings up new game ideas. A few years ago I brought up the concept of a head-to-head dinosaur fighting game, which coincidentally someone else also brought up, but their idea was just two T. Rexes fighting. My original write-up included ideas that finally appeared in the game, such as different species of quickly moving dinosaurs and the concept of the dinosaurs being gods."

The game's graphics were produced via claymation. Development began with a series of production sketches of the fighters drawn by Leong. Using these drawings as a basis, model maker Dan Platt crafted clay model figures of the fighters, for which flexible metal armatures were then cast. The models were airbrushed according to Leong's drawings.

Primal Rage was a major commercial success, although Atari Games derived more profit from its merchandising than from the game itself. RePlay reported the game to be the third most popular deluxe arcade game at the time. Play Meter also listed the title to be the fourth most popular arcade game at the time. Next Generation reviewed the original arcade version, stating, "All in all, an excellent show of graphics and sound design tarnished by unbalanced gameplay."

AllGame's Brad Cook praised the arcade version's visuals, sound, gameplay, and replay value, stating that "This is a fun game and a good value at 25 cents per play with 25 cents to continue." It was nominated for the Video Software Dealers Association's "Video Game of the Year" for 1995, losing to Donkey Kong Country 2: Diddy's Kong Quest.
