Ratchet & Clank is a series of action-adventure platform and third-person shooter video games created and developed by Insomniac Games and published by Sony Interactive Entertainment for PlayStation consoles, such as PlayStation 2, PlayStation 3, PlayStation 4, and PlayStation 5, with the exclusion of Size Matters and Secret Agent Clank, which were developed by High Impact Games for the PlayStation Portable. The series was exclusive to Sony platforms until Rift Apart received a Windows port in 2023. Despite this however, the intellectual property is still owned by Sony Interactive Entertainment. An animated feature film adaptation was released on April 29, 2016.
The games take place in a science fiction setting and follow the adventures of Ratchet and Clank — a feline humanoid mechanic of the Lombax race, and a diminutive, sentient Zoni "defective" robot — as they travel through the universe, saving it from evil forces that consistently threaten it. The series is noted for its inclusion of many exotic, unique and over-the-top weapons and gadgets, a concept that Insomniac Games has expanded into their other games.
Following the development of Spyro: Year of the Dragon, the third installment of the Spyro series, Insomniac Games wanted to move into a new intellectual property, since the Spyro series was owned by Universal Interactive Studios. With the PlayStation 2 recently announced in 2000, Insomniac began to prototype ideas for games on this new console. One, called Monster Knight, never got past the prototyping stage, while a second, called Girl with a Stick and aimed to be a mashup of The Legend of Zelda and Tomb Raider series, had about six months of development work before Insomniac's CEO, Ted Price, decided to cancel it as "the team wasn't feeling it", according to director Brian Allgeier. Now in 2001 and struggling with ideas, Chief Creative Officer Brian Hasting proposed the idea of "an alien that travels from planet to planet, collecting weapons and gadgets", an idea inspired by Spaceman Spiff from Calvin and Hobbes and by Marvin the Martian.
