Primal Carnage: Evolution

Primal Carnage: Extinction is an asymmetrical multiplayer game similar to its predecessor, Primal Carnage. The game pits humans against dinosaurs, with team members on both sides divided into character classes. Gameplay is viewed from a third-person perspective when playing as a dinosaur. Playing on the human team switches the game to a first-person shooter.

Humans have an array of weapons to use, while dinosaurs roar to activate a number of different abilities, although a waiting period exists in between the use of such abilities. Playable creatures include Carnotaurus, Dilophosaurus, the fictional Novaraptor, Pteranodon, and Tyrannosaurus.

The original Primal Carnage was developed by Lukewarm Media and released for Microsoft Windows in 2012. As of 2014, the company was working on a complete rebuild of Primal Carnage, replacing its game code for a less-glitchy gameplay experience. The rebuild, referred to as Primal Carnage 2.0, was initially planned as a free update. Circle 5 Studios took over the Primal Carnage series later in 2014, following disagreements within Lukewarm Media over a planned prequel game known as Primal Carnage: Genesis. The new company consisted of a modding community dedicated to the original game.

Circle 5 announced in October 2014 that the free update would instead be released as a separate game, Primal Carnage: Extinction, which would serve as a sequel. Owners of the original game could purchase the sequel for a discount. In addition to a Windows version, it was also announced that the game would receive a PlayStation 4 port. Primal Carnage: Extinction was co-developed by Circle 5 along with Pub Games, based in Australia. Like its predecessor, the game was created using Unreal Engine 3.

The PlayStation 4 version of Primal Carnage: Extinction received "generally unfavorable reviews" according to Metacritic. The Windows version, upon its official launch in April 2015, was heavily criticized for technical problems that were still present after months of early access. On TechRaptor, Georgina Young said that, "the concept is awesome," but, "bugs and glitches are rampant," calling the game "virtually unplayable" on MacBook Pro (the game does not officially support Mac) and giving it a 2.5 rating out of 10. The PlayStation 4 version was also criticized for glitches.

Matt Adcock of Push Square wrote that "anything with dinosaurs in it should be more entertaining than this". He praised the dinosaur animations but opined that the environments lacked "pizazz", while stating that the humans looked too cartoonish. it was critical of the artificial intelligence and found the use of Unreal Engine 3 to be outdated. Salatiello concluded that the game would have benefitted from more time in development.
