Jak 4 and Jak and Daxter 4 were tentative titles for an undeveloped project by Naughty Dog Inc. The installment would presumably be the first game developed for a rebooted Jak and Daxter series, a topic that Naughty Dog explored before moving onto Uncharted and The Last of Us in 2006 and 2009, respectively. Art released by Naughty Dog in 2014 indicated a dramatic shift from the familiar cartoonistic character design in the original Jak and Daxter series towards a contemporary approach to realistic animation and character design, emphasizing a complete series reboot. Shortly after deciding on the basis of The Last of Us' setting, Naughty Dog decided to forgo a reboot of the Jak and Daxter world and move onto a new IP.
