Jak and Daxter: The Lost Frontier is a 2009 platform game developed by High Impact Games and published by Sony Computer Entertainment. The game is the sixth and final game in the Jak and Daxter series. The player assumes the role of Jak, the angst-ridden hero enhanced by his exposure to Light and Dark Eco. When their world begins to run out of Eco, Jak and Keira travel to the edge of the world in search of the ancient Precursor machinery that could reverse the planet's decline. They're not the only interested factions out on the Brink, however; Jak must contend with Sky Pirates while struggling to control his own Eco powers. Less
