Jak 3 is a 2004 action-adventure video game developed by Naughty Dog and published by Sony Computer Entertainment for the PlayStation 2. The game is the sequel to Jak II, the third game in the series and serves as the conclusion of the trilogy. The game picks up after the events of the previous games and the player takes on the dual role of recurring protagonists Jak and Daxter. It adds new weapons, devices and playable areas. The game was followed by Jak X: Combat Racing. Gameplay Like its predecessor, the gameplay of Jak 3 is a blend of platforming, driving, and gun combat. The player is led through the story as they complete missions, assigned by the various characters in the game. Missions can consist of anything from defeating particular enemies, reaching a specific location, or completing a puzzle. With the exception of timed or otherwise linear missions, the player is free to explore the massive game world as they see fit. Secrets, made available as the player progresses and collects elusive Precursor orbs, can be purchased and toggled, allowing the player to access "cheats" such as upgraded weapons damage, world mirroring, or invincibility. After the game has been completed, the Hero Mode option is made accessible, which, when purchased, allows the player to replay the game at a higher difficulty level, but with all previously unlocked cheats and extras still available. As the Precursor Orb count is not reset, and the orbs are regenerated at their original locations, the player is able to regather orbs that they had already collected the previous time they played through the game. Collecting all 600 Precursor Orbs has some cosmetic effects on Jak's appearance, but has no effects other than this. In Hero Mode, Jak also keeps all twelve of his weapons but loses his light flight along with two of his dark powers until they are collected in their respective parts of the game. 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
