There are some differences between "Jak 3" and "Jak II". Most notably are the changes undergone in the Haven City environments. Spargus City, the Wasteland, and Haven City function as the main hubs in "Jak 3", where leaper lizards, buggies, and zoomers respectively are the main sources of transportation. While "Jak II" provided the player with only four different types of guns, "Jak 3" expands on the concept with two additional modifications for each gun giving Jak a powerful loadout of twelve weapons. Also, the "Dark Jak" form, introduced in "Jak II", which allowed the player to transform into a more powerful offensive version of Jak, is countered by a "Light Jak" form that mainly focuses on defensive abilities. The jet-board makes a return appearance from "Jak II" to this game, with some additional upgrades as well.
