The gameplay of "Jak II" is significantly different from . The Eco timed power-up gameplay from the previous game has been removed, and introduction of weapons such as the Morph Gun, a multipurpose firearm, adds a greater emphasis on enemy combat. The player can unlock four different gun mods for the gun as they play through the game; the shotgun-esque Scatter Gun for close range fighting, the semi-automatic Blaster, for long-range fighting, the Vulcan Fury, a high rate-of-fire weapon in the fashion of a minigun, the bullets of which deal less damage per round compared to the Blaster but are able to pierce enemies and breakables so it can hit multiple targets with a single round, and the Peace Maker, which fires charged blasts of energy, and is extremely powerful, chaining an instant kill energy between enemies that are in close proximity to each other.
