access new missions by visiting various allied characters. These missions serve as a replacement for the previous game's Power Cell collection driven gameplay in the first installment of the series. Throughout the game, the player can collect Precursor Orbs which are sparsely dispersed throughout the various worlds. The Orbs are non-essential to completion of the game but allow the player to unlock cheats and other "secret" content. Jak can traverse the large city using hover vehicles and a jet-board which allows him to hover across water and grind on rails. Due to experiments conducted on him for two years, Jak has also gained the ability to manipulate Dark Eco to transform into a darker version of himself known as Dark Jak. The form is only accessible after Jak has absorbed enough Dark Eco to charge his ability. Dark Eco drops from slain enemies and can occasionally be found in red crates scattered throughout the world. In his Dark form, Jak becomes much more agile and his melee attacks become more powerful but he loses the ability to use the Morph Gun. Jak 2 also introduces a "currency" known as Metal Head skull gems. By collecting these skull gems which are dropped by most Metal Head creatures when defeated, Jak can gain additional abilities for his dark form and play minigames at kiosks throughout Haven City. The Dark Jak abilities that can be unlocked can be used to unleash devastating attacks that kill all enemies within the vicinity at the cost of ending his Dark form immediately after the attack. Plot Setting Jak II takes place in the same fictional universe created by Naughty Dog for Jak and Daxter, though five hundred years after the events of the first game. The game largely revolves around Haven City, a dystopia ruled by Baron Praxis and his Krimzon Guard law enforcers. Haven City serves as the game's hub location, although the player is frequently given tasks that must be fulfilled outside of the city. Characters Jak (voiced by Mike Erwin) is the game's protagonist, along with his sidekick Daxter (voiced by Max Casella). When they first arrived in Haven City, Jak was captured by Krimzon Guards and became the subject of Baron Praxis's (voiced by Clancy Brown) "Dark Warrior" project. He became subjected to several experiments, ultimately giving him the ability to become "Dark Jak", a beastly version of himself which is unleashed
