Jak and Daxter: The Lost Frontier is a platform game developed by High Impact Games and published by Sony Computer Entertainment. It was announced on April 1, 2009 and was released on November 3, 2009 for the PlayStation Portable and PlayStation 2. The player assumes the role of Jak, the angst-ridden hero enhanced by his exposure to Light and Dark eco. The game received a generally positive response, with critics praising the game’s graphics, gameplay and aerial fights.
Similar to other games in the series, Jak and Daxter: The Lost Frontier features a Hero Mode where players are able to replay the game. Weapons, armor, powers, secrets, and unspent Precursor orbs are retained through each playthrough.
Jak and Daxter: The Lost Frontier was originally planned as a PlayStation Portable exclusive and was in the process of being developed by Naughty Dog when it was cancelled. Evan Wells revealed that they were unable to sustain the games development alongside Uncharted 2: Among Thieves and made the decision to pass the project onto High Impact Games.
The game begins with Jak and Daxter, escorting Keira on her journey to become a Sage and help to find the reason for a worldwide Eco shortage. After an encounter with Captain Phoenix, an Eco-seeking Sky Pirate, Jak crash-lands on an island at the Brink (the edge of their world) and sets off in search of Eco with which to repair his Hellcat. After a successful take-off, Jak must fight off Sky Pirates attacking the ACS Behemoth, an aerial warship captained by Duke Skyheed of Aeropa. Jak is given an instrument called the Eco Seeker. He is unable to power it because the Eco instability prevents him from using his own Eco powers (along with preventing him from turning into Dark Jak), but Keira is granted permission to study it for a week if Jak proves himself in a test of his fighting skills. Daxter falls into the sewers of Aeropa on the way back, where he becomes tainted further by Dark Eco and is temporarily transformed into “Dark Daxter”.
